The aim of this project is to investigate the detection andemission of terahertz radiation by using graphene-based
devices with asymmetric dual grating gates. The deviceswere
fabricated and characterized under terahertz excitation of 0.15
- 0.60 THz. The measurements were performed at 4K. Bothgraphene (Gr) and hexagonal boron nitride (h-BN) layers
were obtained by the mechanical exfoliation technique. The
Gr was encapsulated between two layers of h-BN to make thevan der Waals (vdW) heterostructure that leads toimprovement of the carrier’s mobility. The technique used isbased on the hot pick-up method. The fabricated vdW
heterostructures (h-BN/Gr/h-BN) were deposited on a doped
silicon substrate with a SiO2 top layer (Si/SiO2). Due topandemic situation, it was not possible to fulfill the exchangeof students as intended and, eventually, the planned
measurements were eventually performed at Salamanca
University.

An exfoliated graphene was sandwiched between two h-BN
layers. The hot pick-up technique was used for the fabricationof the double heterostructure (h-BN/Gr/h-BN) and Raman
spectroscopy was used to ensure the presence of the graphene
layers as well as the h-BN layers (Figure 1). Asymmetricgrating gates were deposited on the h-BN top layer as shown

ղ Detection of terahertz radiation using theADGG-GFET.
The fabricated devices were characterized electrically withboth back and top gate at 4K (Fig.3). The mobility was
extracted from the dc measurements using the Kim et al.
model. The electron carrier mobility was around μe ~ 22784
cm2/Vs and for the holes around μh ~ 17339 cm2/Vs.

Figure 3: Channel resistance measurements of the ADGG-GTeraFETasa function of (left) back gate where VTG2=0V and (right) the top gate 2 atdifferent VBG =-2 to -5 V.

The ADGG-GFET FETs was placed inside an opticalcryostatand then excited using an electronic source at 0.3THz

共同プロジェクト研究and 0.6 THz. The photoresponse was measured using thelock-in technique with a chopping frequency around 298Hz.
No DC bias current was applied to the device. Figure 3-(a)shows the measured the temporal photoresponse when theTHz source was switched on and off. A clear signal of around
was measured at both frequencies. Figure 5-(a) shows thephotoresponse as a function of the back gate voltage obtained
at 4K and under excitation of 0.15 THz. An enhancement up
to -4mV was observed at VBG=-9V & VTG2=+1V. When
applying a negative voltage on the back gate while
maintaining the top gates positive, a periodic region of carriersof opposite sign are created along the channel, in the regions
below back and top gates.

Figure 4: Temporal photoresponse signal when the THz source (0.3 and0.6 THz) was switched on and off.

Those conditions create the plasmonic ratched effect that is
responsible of the rectification of the terahertz radiation.
Similar behavior was observed when the device was excitedwith radiation at 0.3THz (Fig.5-(b)) and at 0.6THz (Fig.5-(c)).
Under excitation of 0.3THz, an enhancement up to 6mV wasobserved for VBG =-6V, VTG2=-1V and for values of
VBG<-10V, VTG2=1V. However, under excitation of 0.6THz,
no noticeable difference was observed when applying ±1V on
the top gate 2 and a maximum of 1.3 mV was obtained at VBG≈-6V. Due to the biasing of the different gates, there exist
different regions along the channel with different carrier types
and concentration: (i) regions under the top gate 1 controlled
by VTG1=0V and by the VBG (ii) regions under the top gate 2controlled by VTG2 and by the VBG and (iii) ungated regions
controlled only by the VBG. We observed a different
behavior of the photoresponse with the excitation frequency
which can be related to plasmon inside the different regions,with different sizes. The rectification under excitation could
be related to the regions under both top gates and the one
under 0.6THz to the ungated regions. More measurements
and simulation are needed to highlight the effect of eachregion in the measured signal.

- Both groups has a solid strategic experience in theprocessing and the fabrication of graphene-based devices aswell in their characterization.
- New devices were fabricated in Salamanca. There are only
a few groups in the world that can fabricate this type ofdevices. The group of Manchester University leaded by theNobel laureate A. Geim is one of them.
- Investigation of plasma oscillations using novel devices
based on new 2d material like graphene is of great importancefor the fundamental physics as well as for the development ofreal applications like terahertz detectors/emitters.

The capability to manipulate and control
antiferromagnets (AFMs) via electrical techniques has
provided unprecedented opportunities for thedevelopment of materials, and new-concept electronic
devices with different functionalities. Previous works
utilizing
AFMsinquasi-three-dimensional
heterostructure geometry have demonstrated
promising characteristics such as electrical control of
antiferromagnetic Néel vector and stabilization of
AFM skyrmions, expected to pave the way for future
AFM-based memories and devices for unconventional
computing architectures. On the other hand, there has
not been much focus on low-dimensional (layered andchainlike) AFMs, fundamentally and technologicallyinteresting due to their abilities to introduce newfunctionalities and translate the existing properties
down to the two-dimensional (2D) limit. Among thedifferent families of layered AFMs, layered
TaFe1+xTe3 (TFT) is interesting, where the Fe atoms
form a two-leg ladder along the principal axis but witha zigzag shape representing an intriguing quasi onedimensional magnetic system. TFT crystallizes in a
monoclinic structure, consisting of Ta-Fe bonded
layers sandwiched between the Te layers. There arealso excess Fe atoms, randomly occupying someinterstitial sites, potentially influencing the magnetic
order in the Fe-Te layers.
In this work, we have explored the magnetic,
temperature, and angle-dependent MR effects inlayered AFM TFT. Temperature dependent
magnetization measurements show antiferromagnetic
ordering at § 200 K. An applied magnetic field (H)perpendicular to the (10-1) plane shows the existenceof a spin-flop transition at T § 130K, associated withan increase of M and an abrupt drop of the longitudinalMR, only for H٣ (10-1) plane. Interestingly, the spinflop transition also results in a sharp deviation of theangle-dependent longitudinal MR behaviour from its
usual harmonic nature, manifesting in a strong
anharmonicity in angular dependence. Besides, there
is a significant enhancement of longitudinal MR,

compared to H || (10-1) configuration. Our work
deepens the understanding of MR properties in layered
AFMs and indicates the possibility of utilizing thisMR effect as a prospective scheme for introducing
spintronic functionalities in layered AFMs.

Single crystals of TaFe1.25Te3 (TFT, hereafter) weregrown by the chemical vapor transport (CVT) method.
A stoichiometric mixture of Ta (3N), Fe (3N), and Te(3N) was ground thoroughly and sealed in an
evacuated quartz tube along with TeCl4 as thetransport agent. The tube was kept in a two-zone
furnace at a temperature gradient of 690 ƕC/660 ƕC.
Needle shaped crystals were obtained after ten days.

Figure 2(a) shows the schematic diagram of themeasurement geometry, and the definitions of theazimuthal (angle ‫ ׋‬between H and I) and polar (angle ș
between H and I) angles with respect to the single crystal.
An applied dc I (|| (10-1) plane) was passed through thesingle crystal along the x direction (i.e., along the crystal
plane). The resulting change in longitudinal or transverse
voltages were measured under rotation of external H of
constant magnitude along the azimuthal and polar planes.
Intuitively, ș sweep corresponds to H rotating from amagnetic hard (ș § 0°) to easy (ș § 72.4°) direction,compared to ࢥ sweep, enabling us to quantitatively109共同プロジェクト研究)LJ  D  6FKHPDWLF UHSUHVHQWDWLRQ RI WKHPHDVXUHPHQW FRQILJXUDWLRQ XWLOL]HG LQ WKLV ZRUN

Figures 2(b) and 2(c) show experimental results of ȡH
versus ‫׋‬, under constant H and T. We observe that ȡH
versus ‫ ׋‬follows a twofold symmetry with a sin2‫׋‬behaviour [solid lines in Figs. 2(b) and 2(c)]. Owing to
the A-type AFM order along with the absence of spinflop configuration for H|| (10-1) plane, the observed
magnetoresistive behaviour can be interpreted as
anisotropic magnetoresistance (AMR). On the other hand,significant deviations from the conventional AMR wereobserved for H rotations along ș [Figs. 2(d) and 2(e)]. ȡT
versus ș curves deviate significantly from the harmonic
behaviour and show a sharp sign reversal as H٣ (10-1)
plane. Interestingly, the anharmonic behaviour isstrongly dependent on H [Fig. 2(e)], and weakly varies 1.
with T [Fig. 2(d)]. We speculate that the anharmonic
nature might be strongly influenced by the magnetic
anisotropy of TFT, preferring an AFM alignment2.
perpendicular to the (10-1) planes. To further explore thepeculiar nature of the magnetotransport features of TFT,
we also study the effect of H rotation (ș) on ȡL [Figs. 2(f)and 2(g)]. For applied H less than the spin-flop field, theMR curves show a harmonic behaviour. Interestingly, as
H is larger than the spin-flop field, we observe asignificantly different behaviour, strongly anharmonic in

110

nature with the appearance of plateau-like features forcertain ș, along with a significant increase in themagnitude of ȡL. Furthermore, an increase in T, in thisregime at fixed ȝ0H = 8 T, also results in a reduction ofȡL magnitude, attributed to an enhancement of spin
fluctuation near TN.
We believe that our results will inspire future
experimental investigations with the variation of numberof layers which might initiate a new paradigm of AFM
spintronics with layered material systems. The present
experimental results provide considerable insights into
the remarkable magnetic and magnetotransport feature oflayered AFMs and suggest an alternative scheme tointroduce novel spintronic functionalities in layered
AFMs.

Stimuli Corpus (Chen et al., 2009). For each data base, we
selected 7 basic facial expressions (Ekman, 1992): Angry,
Disgusted, Fearful, Happy, Neutral, Sad, and Surprised.
For each database, we selected 4 male and 4 models thathas the highest facial expression recognition accuracy or
highest expression intensity/arousal for each database.
Thus, there were 168 selected images (3 databases x 8
models x 7 expressions) in total.

㹙2㹛◊✲⤒㐣 (Summary)The collaboration this year was conducted via
tele-communication and in-person. We set up the online
experiments successfully before Dr. Chien-Chung Chenpaid a visit to Tohoku University in February. During his
visit, we analyzed the results and drafted a paper. Further
discussion was also made to examine future work
opportunities.

Facial expressions are perhaps the mostefficient ways to communicate emotion. They are also
critical cues for online communication when other bodily
cues are not available. Facial expression recognition,
however, showed a strong racial effect: it is harder torecognize certain expressions on an individual from a race
different from the observer (For a review, see Biehl et al.,1997, J. Nonverb. Behav.). This may have a negative
effect on international communication. The purposes ofthis research are (1) to identify the racial effect in facial
expression recognition between Japanese and Taiwaneseand (2) to develop a computational model to characterizesuch effect.
We have adopted images from three face data bases
suitable for our cross-cultural comparison studies: (1)Caucasian: Ekman’s POFA Database (Ekman & Friesen,
132

From the results, we selected target images from each of
the 3 databases (1 M and 1 F each) which satisfy thefollowing criteria: (1) high accuracy by both JP/TW
participants, and (2) distinct cultural differences between
JP/TW participants. It turned out that fear was the key
emotion that exhibited this quality most. We next morphed
the selected face along the angry-fear at 5 points: 1%, 25%,
50%, 75%, and 99%.

We asked the subjects to judge the expression (angry or
fearful) of composite faces that were the combination of
the upper and lower face images with different morphinglevels between the two emotions (fearful and angry). 5 JP
participants and 5 TW participants joined the experiment.



共同プロジェクト研究We observed cultural differences (but not ORE) between
JP, TW, and CA observers to process facial emotions. Thisdifference may originate from expressions, e.g. TW use
more lower face portion to express anger/fear than JP. This
does not apply to happy-sad faces, which suggests anemotion-specific consideration required to understand thisphenomenon.

We used a multidimensional signal detection theory(Ashby, 1992) to construct a model to fit our results. Thismodel included an angry and a fearful emotion detector (inExp1), each has a bivariate Gaussian sensitivity function
on the feature space. A covariance matrix represents theinteraction between upper and lower faces. The probabilityof judging a morphed stimulus as an angry/happy face
was plotted as a function of the angry/happy level of upper
faces (see right), together with the model predictions (solidline). The same for Exp 2 except the detectors are forsadness and happiness.

We did not observe a clear main effect of race across two
experiments. Rather, we discovered an interaction
between the races of the participant and the models. Suchinteractions are expression dependent. Participants
incorporated less lower face for fear-anger discrimination
than discriminating sad-happy faces. The 3 cultural groups
are more similar in their weighting of upper and lower
face info while discriminating sad-happy faces thanfear-anger discrimination.

Our facial expression perception model is based on amulti-dimensional signal detection theory (Ashby, 1992)
to account for cultural effects on emotional expressions.
There is an angry and a fearful emotion detector, each has
a bivariate Gaussian sensitivity function on the feature
space.. The response of a detectors is a nonlinear functionof the morphing level divided by the inhibition from otherfilters, represented by a covariance matrix. The visualsystem sums the response in each detector across the facethen compute the likelihood of each expression type based
the summed responses. The probability of a decision is acumulative Gaussian function of the likelihood.

None.

Japanese participants used mainly upper face forfear-anger judgement, with the exception of viewing
Taiwanese faces. It’s possible that Taiwanese are more
expressive in their lower face for anger.

In this project, we have been working on devising a novel
IoT framework that we name as KIBAN with a view torapid expansion of IoT through mass adoption bycommon people who do not possess specialized
knowledge. We also propose a novel hierarchical edge
computing architecture called Dynamic HierarchicalEdge Architecture or DHEA to overcome the potential
issues with the centralized cloud-based approach. We
describe how KIBAN could be realized using the DHEA
architecture. Because of the layered structure of KIBAN,
it is possible to easily implement part of the platform
even on gateways with low computing capabilities.
Experiments show that such implementations can lead tofaster response time and often leads to increased
efficiency compared with that in a cloud-based system.
Like last years, in the current year of the research project,
we particularly focus on implementing components of
the Knowledge and Intelligence Layer (KIL) for learningand interpreting texts available on the web in the form of
posts in the social media, product review, articles in the
web etc. With a view to addressing online texts
irrespective of the language, we have been analysing
texts in several languages like Japanese, Bengali andThai languages. We have been trying to understand thecharacteristics of each language and the inherent
similarities or differences. Learning from the web text
data and interpreting the intentions of the posts leads tooffer many services by the other layers of KIBAN
platform (Fig.1), for example, Big Data Service Layer(BDS) efficiently.
Two researchers, the Principal Investigator (PI), andProfessor Dr. G. Hasegawa have been involved in thisresearch. The Principal Investigator (PI) expresses deep
gratitude for the generous support that the RIEC
Research Collaborator, Professor Hasegawa had
extended during the project.

ձ Realization of components of KIBAN IoT platform
In the first year of the research, we proposed a newgeneration IoT platform, KIBAN (Fig. 1), toward therapid evolution of IoT. It consists of the following six
layers.
z Data acquisition and storage layer (DASL)z Knowledge and intelligence layer (KIL)z Big data service layer (BDL)z Open software layer (OSL)z Presentation layer (PL)z Security and privacy layer (SPL)
So far, we have been engaged in implementing different
elements of several of the layers, particularly the dataacquisition and storage layer and the knowledge andintelligence layer. In addition, we emphasized on
proposing the functionality of the security and privacy
layer (SPL). It has been observed that IoT gateway anddevices are often prone to malicious attacks throughunauthorized access by third parties. Hence, we proposedmechanisms for access control through multi-factor
authentication. Regarding analysis of web data, we haveso far attempted (1) learning from web data in the formof product review in Japanese language and figure out thesentiment expressed in the reviews. (2) assuming thegender of the poster of posts in Bengali language in the
SNS like Facebook. We are also working on extending
this to Japanese language. This year, we aim at learning
about sentiments expressed in Thai language web texts.

platform. Toward this goal, we focus on huge data that isavailable in the web like the social networking services(SNS), comments or expressions in blogs, reviews inonline shopping sites etc. Here, we report the outcome ofour research on learning about sentiments expressed in
online text in Thai language. The general problem ofsentiment analysis is currently being addressed for texts
in different languages using both traditional and deeplearning methods. The analysis of texts in different
languages usually depends on several factors. The first is
the organization of the sentences in written form. If thewords in a sentence are written separately like it is done
in English, it is possible to identify each word as it is.
However, if the words are written continuously without
separation like it is done in Japanese or Chinese
languages, efforts should be made to identify each words
accurately from the sentence. The next issue is the use ofirony. Sometimes, in some languages, it is possible toexpress some negative opinion without using any
negative word. Such expressions are difficult to analyseusing machine learning.
A. The Challenges of Thai Language
In written form, the Thai language has 44 consonants, 21
vowels, with 32 different voices and 4 tone marks.
Normally, Thai messages are constructed horizontallyfrom left to right without the interval between words toform a sentence. Hence separating them correctly toidentify words often poses a big challenge. In addition,use of irony can make understanding of the real meaningof the sentence difficult. Furthermore, in SNS media,
language used is often distorted that makes it moredifficult to understand the emotion of the poster. In thisresearch, we produce a Machine learning model toproceed with the text message to extract the sentiment of
the user in a message.
B. Dataset Creation
We utilize the “Wisesight” corpus for training and testingdatasets. The dataset contains 26,737 separate text datain positive, negative and neutral categories. We utilize
11,601 sets of text data belonging to either positive or
negative categories. In addition, we collect the customer
review from an online-market platform called Shopee as
an additional test dataset.
The processing of the data involves word tokenization,text vectorization, word embedding (Fig. 2).
C. Word Tokenization
It is the method to separate the word in the sentence.
As mentioned above, in Thai language written sentences,every word in the sentence is adjacent. While in English,
each word in a sentence is separated by spacing. Thus,
we need to extract each word in every sentence in orderto prepare the dataset for the next stage of processing. For
this task, we apply the Thai NLP library called
PyThaiNLP which has the tokenizer to deconstruct thesentences into words.
D. Text Vectorization
It is the preprocessing layer that maps text features after

applying word tokenization into an integer sequence.
Text vectorization from TensorFlow is one of thevectorization techniques that we employ for this work.
E. Word Embedding
The TensorFlow Word Embedding layer provides a way
to convert the data into a dense vector of floating-pointvalues.

F. Deep Learning methods
Different deep-learning methods were then applied tolearn from the data and their performances were tested.
With a view to achieving better accuracy, we deploy Bidirectional LSTM (Bi-LSTM), Bi-directional GRU (BiGRU), CNN and their combinations.
G. Evaluation
From the Wisesight dataset, 11,601 data that correspondto either positive or negative sentiment were used in our
experiments. Among them 1,161 sets (478 positive, 683
negative cases) amounting to 10% of the data were set
aside for testing. In addition, we tested 100 reviews (50positive, 50 negative cases) from online marketplace
named Shopee.
Table 1 shows the accuracy of sentiment analysis of Thai
language texts using different deep-learning models. The
combination of Bi-LSTM and CNN yields the best
results.

Touch has become the main input modality for mostinteractive electronic devices, providing intuitive user
experience of direct manipulation of content. However, touch
interaction is still limited to fewer input modalities. This often
becomes a problem when task scenarios involved switching
between multiple modes of operation, such as navigating in amap, drawing on a canvas, or playing a game.
In this research project, our goal is to explore low-cost andpower-free interfaces that expand input vocabulary of touch
devices thereby enriching user interaction with touch devices
with less fatigue. In this year, we have worked onsummarizing our research findings obtained until the last year
and publish them.
Project members communicated both in-person and online,with the purpose of discussing the paper structure andcontents before submission, how to revise the paper after the
first review, and how to present a talk after its acceptance.
Specifically, the meetings were held on April 14 (in-person),May 31 (in-person), June 30 (in-person), October 31 (online),

The main objective of this project was to investigate culturaldifferences between elderly Thai and Japanese users. The
COVID-19 pandemic had been a significant obstacle toachieving the project's aim. In 2020, the project's goal was
adapted to investigate differences between two age groups, i.e.,
the elderly Thai group aged 55 years old and over and the Thai
users aged 45-55 years old. In 2021, researchers of this project
still could not conduct a usability test as the Thai government
strictly enforced the social distancing policy. So, following thethematic analysis, the researchers developed a preliminary
codebook for analyzing the observation notes taken during theusability tests in 2018-2020.
Around October and November 2022, after the Japanese
government announced that the country was open for tourists andshort-term visitors from abroad, the project's researchers planned
to go to Sendai to conduct a usability test with elderly Japaneseusers. However, the researchers encountered another difficulty inrecruiting Japanese older adults in Japan. Finally, the Thai
researchers and Japanese collaborators managed to recruit foursenior Japanese users living in Bangkok, Thailand, to participate
in the study.
In summary, some usability issues found were similar between
the senior Thai and Japanese groups, for example, difficulty infiguring out how to use the multitouch function.

㸦3-1㸧◊✲ᡂᯝ (Research Results)
Below are key findings from the usability study, which aresimilar between the senior Thai and Japanese users.
x The Japanese older adults could not figure out how
to use a multitouch function. The reason was thatno signifiers informed the users that they could use
multiple fingers to select more than one photo andsee groups of similar images.
x It was difficult for the users to notice the scroll barsof the menu ‘Date,’ ‘Saturation,’ and ‘Luminance’
because the colors of the scroll bars were similar tothe background. Moreover, the position of thescroll bars for ‘Saturation’ and ‘Luminance’ on theleft and right of the screen, respectively, made it
hard for the users to see them. The numbers ofsaturation values and luminance values were also
hard to understand.
x The Japanese users preferred using the menu inJapanese, if possible.
Photos taken during the usability study are shown below.

Although the researchers could collect the data from four seniorJapanese users, the results show that the usability issues andquestions raised by the elderly Japanese users were not drasticallydifferent from the elderly Thai users. In conclusion, there were no
significant differences between the two cultures. The usability
findings from the senior Japanese users could be added to theexisting results learned from the Thai group.

Institute of Technology (RIT) where the principal investigator(PI), Dr. Sungyoung Kim, belongs to. From the summer(August) of 2022, one Ph.D. candidate, Akira Takeuchi,joined RIT and worked with Dr. Kim on the same topic. As ateam, we have conducted a series of new experiments that aim
to find both behavioral and biological supports of individual
difference induced from cognitive characteristics. We foundthat at the low SNR condition, meaning that the noise masker
became more dominant and distracting, the interdependent
self-construal group showed a significantly larger scoredeviation between the front- and back-masker conditions
compared to the independent self-construal group. No clear

difference between groups was found when the SNR was
high. This result coincides with the hypothesis of the project(please see the previous reports of 2020 and 2021) as well as
the pertinent publications [Kim and Martens, 2007; Kim et al.,2015].

The PI conducted a pilot study focusing on therelationship between social orientation (and sense of self) andauditory selective attention. We hypothesized that listeners
who tend toward a sense of an interdependent self (selfidentity defined through relationships with others) would
allocate greater attention to background and contextual
auditory information than those who tend toward a sense of
an independent self (self-identity defined independently ofothers), thus affecting their spatial auditory selective attention
ability. A total of 24 listeners participated in this experiment.
They first completed a survey that measured their sense of self
via the self-construal scale (SC) [Singelis, 1994]. The results
showed that the group consisted of 10 listeners with aninterdependent self-construal and 14 listeners with anindependent self-construal. As mentioned above, ourhypothesis is that the interdependent group would pay more
attention to the masker from the back than the front comparedto the other group. As Figure 1 illustrates, at the low SNR
condition (-18dB, left bar of each panel), meaning that thenoise masker became more dominant and distracting, theinterdependent group showed a significantly larger scoredeviation (p = 0.0183) between the front- and back-masker
conditions compared to the independent group. No clear
difference between groups was found when the SNR washigh (-12dB, right bar of each panel).

Currently, little experimental data exist to support orrefute the significance of cultural influences on speechunderstanding-in-noise (SiN). The significance of this study
lies in the discovery of a measurable cognitive construal that
influences a crucial auditory process, selective attention for

spatial hearing. This finding could be applied to accurately
assess an individual's hearing difficulty in noisy environments
and could lead to the development of novel auditory devices,such as hearing aids, that are optimized for a user's specificcognitive profile.

Figure 1. Data collected from 24 participants, which shows difference in correct answer rates between “collocated” and“separated” condition. The collocated condition is where the masker and target were generated from the same front
direction while the separated condition is not. When the signal-to-noise ratio (SNR) is small (indicating that the task was
relatively easy), there was no big difference between two listener groups (Interdependent (left) and independent (right)).
However, when the SNR gets lower, the difference became significant (p = 0.0183). This result indicates that theinterdependent self-contrual group was more distracted by the spatially separated masker condition, generating a bigger
difference between two (collocated and separated) condition. This result lies in line with previous research reports that theinterdependent people are more sensitive to given environment and try to understand it holistically.


We have proposed the two approaches that both
imply tight photocarrier confinement within thesemiconductor surface, that is essential for THz
emission enhancement of a photoconductive emitter.
The first approach proposes the new design which isbased on an implementation of a densely packed
sapphire fibers mounted on the emitter’s surface. The
design is used to enhance the overall performance ofthe emitter thanks to wonderful optical properties ofthe sapphire fiber in the THz frequency range
providinghighopticalcontrastatthesemiconductor/sapphire interface. We demonstrated a
40-fold THz power boost compared to conventional
emitter [P1].
The second approach relies on the high-aspect ratio
plasmonic grating emitter, which enables a 104 THzboost compared to conventional emitter without
grating thanks to the excitation of higher-orderplasmon guided modes in Au slits [P2].
The both approaches have demonstrated theirstability and feasibility. Overall, the emitters allow a
4.5 THz bandwidth with a 65 dB dynamic range.㹙3㹛㹛ᡂᯝ (Results)㸦3-1㸧㸧◊✲ᡂᯝ (Research Results)
Approach 1.
We have proposed to use a high refractive sapphirefiber lens to enhance the overall THz power in aphotoconductive THz emitter. Using numericalsimulations, we showed that the lens provides a spatial
redistribution of the photocarriers density in theantenna’s gap. Then, by optimizing the diameter of thesapphire-fiber, we demonstrated the possibility toenhance the coupling of the incident electromagnetic
waves at the interface between the sapphire fiber andthe semiconductor with the antenna terminals by afactor of ‫׽‬40 compared with the case without the fiber,

boosting the total efficiency by a factor of ‫׽‬7–10.
Furthermore, we note that in practice, the incident
laser beam is featured by a diameter of 1.0–1.5 mm.
Thereby, the number of stripe line pairs on the highpower emitter chip will be approximately 5 for d = 220μm and g = 10 μm. Therefore, to increase the overall
performance, one can use 10 pairs of 5-μm-gap strip
lines (d = 110 μm).

EM wave with Ȣ = 780 nm.

distance. LAE is a large-area photoconductive THz emitter.

Approach 2.
We propose the design of a photoconductive emitterwith a plasmonic grating featuring a very highplasmonic Au electrode with a thickness of 170 nm.
As we show numerically, the increase in h

THz imaging, for instance, in biomedical, nanooptics and photonics applications.

significantly changes the electric field distribution,owing to the excitation of higher-order plasmon
guided modes in the Au slit waveguides, leading to an
additional increase in the emitted THz power. We
develop the plasmonic grating geometry with respect
to maximal transmission of the incident optical light,
so as to expect the excitation of higher-order plasmon
guided Au modes. The fabricated emitter canefficiently work with low-power laser excitation,
demonstrating an overall THz power of 5.3 μW overan ‫׽‬4.0 THz bandwidth, corresponding to aconversion efficiency of 0.2%.

- Both groups are gaining strategic experience in theprocessing, development and fabrication of highpower photoconductive THz emitters as well as intheir characterization.
- New devices and the approaches as well, were
fabricated and characterized together with the
RIEC’s group of Prof. T. Otsuji and also in Moscow.
There are only a few groups in the world that canfabricate these types of THz devices. Among them
we should notice the groups of Profs. M.

In recent years, substantial advancement has
occurred in the study of the magnetic, optical anddielectric properties of nanomaterials such as
nanoclusters, quantum dots, or 2D materials. They
are used particularly in permanent magnets,
magnetic recording media, microwave absorption
devices, ferrofluids and biomedical applications. For
certain applications, it has been shown the use of bimagnetic core/shell nanoparticles (Bilayer 2D
materials) can be advantageous over single magnetic
nanoparticles (Mono-layer 2D materials). In his
project we aim to study the physical properties ofnanostructures that can be exploited for theengineering of new material and nanostructuredevices to make novel terahertz (THz) applications.
Research in the THz technology is facing many
challenges in both physics and engineering, but㻌
having more insights in materials properties and newnanostructure design will be the needed
breakthrough to come up with compact and efficient
THz devices. We will use the methods of Monte
Carlo and ab-initio simulations to prove theconsistency of the antiferromagnetic coupling inmaterials. This unique coupling could give rise to
more advanced applications of bi-magnetic
core/shell nanoparticle or bilayer 2D materials,
including graphene and other widely researchednanomaterials. Based on the theoretical calculations,
we will fabricate and characterize new devices basedon the studied 2D heterostructures toward terahertz
detection and emission. The work will pursue thecollaboration between the PI team at UAE
University, UAE and the host researcher team at
RIEC, Tohoku University, Japan. The major impactof this project will also be to study thethermodynamic properties of these nanostructures,
which are the key properties for magnetic anddielectric devices that remain unknown.

In the frame of this project, the PI from UAE
University visited the host researcher team at RIEC,
in the period of June 13th-24th, 2022. During this visit,
several meetings were organized with Prof. Otsuji
and his team to work on experimental transfer of 2D
materials, and we were able to experimentallytransfer a few layer MoS2 thin film on top ofGraphene channel in a GFET structure. We also
made plans to investigate perovskites devices using
the THz experimental setup available in Otsuji labs,
but due to a recent earthquake, the experimental
setup needed further calibration. During this visit, on
June 23rd, 2022 from 17:00 to 18:00, an open
seminar to RIEC faculty and students was organizedto highlight the recent work of the PI at UAE
University in the field of 2D nanomaterials.

㸦3-1㸧◊✲ᡂᯝ (Research Results)
During FY2022, we have developed computationalmodels to investigate the voltage tunability of THz
nanoribbon
absorptancein
MoS2/Graphene
heterostructures (Figure 1). We were able to realize athin THz absorber that can be easily tuned through thewhole THz range (0.1 THz-10 THz) by applying a low
gate voltage (< 1 V) (Figure 2). The computationalmodel showed that we can achieve absorptance ofapproximately 50 % of the incident light, which is
twice that of graphene-only nanoribbons, the structure
performance is not affected by high temperatures (500
K and above) (Figure 3).
We also varied the nanoribbon width wn from 90 nm
to 300 nm while keeping the same spacing d between
the nanoribbons as 10 nm. A shift in the absorption
frequency towards low energy frequencies (low THz
frequencies) occurs with increasing the nanoribbon
width. Decreasing the widths less than 90 nm shifts theabsorptance spectrum to the right, outside the THz
region (Figure 4). Decreasing the nanoribbon width
increases the band gap and so we can have electrontransitions at higher energies/frequencies. Increasing
the substrate thickness of SiO2 (dsub) shifts theabsorption frequency to higher frequencies and causes
a little increase in absorption for different gate
voltages as shown in (Figure 5). In order to have agood tunability in the THz region by varying the gate
voltage, we have to use a small substrate thickness in
the range of 5 nm. This can be attributed to the factthat the carrier concentration of graphene is related tothe substrate thickness according to developed model.

Despite the fact that the simulated structures are
expected from a theory point-of-view to show highelectronic and optical properties, which will improve
the sensitivity for THz detection, the experimental
results show few limitations related to the degradationof the plasmon frequency due to the dimensions of theribbon, and the degraded mobility values. Solving
these issues, will promote these structures as THz
devices, and can lead to a new era of low-cost andcompact terahertz imaging systems and to develop
ultra-high-speed THz wireless communication.
Besides, it was found that there is a great potential for
the MoS2/graphene heterostructure, and BP/graphene
heterostructure as good alternative nanomaterials forthe design of photodetectors and transistors forapplications in THz technology.

We build a solid basis for this proposal
demonstrating that that the plasmonic oscillations
can substantially increase the device response [1,2]and our proposal was funded. Working on the
proposed topic we demonstrated that thenonlinearity due to the Coulomb drag of
quasi-equilibrium carriers by injected ballistic
carriers of lateral n+-i-n-n+ graphene field-effecttransistors (GFETs) can be used for effective
resonant detection of THz radiation, moreover theplasmonic oscillations in a GFET channel enables
a strong resonant enhancement of the response [3].
As the resonant plasmonic detection dramaticallyincreases the sensitivity of the terahertz detectors,
we proposed detectors based on a gated graphene
p-i-n (GPIN) field-effect transistor (FET) structure[4]. In the proposed device, the gated p and nregions serve as the hole and electron reservoirs
and the terahertz resonant plasma cavities. The
current-voltage (I -V) characteristics are strongly
nonlinear due to the Zener-Klein interband
tunneling in the reverse-biased i region between
the gates. The terahertz signal rectification by thisregion enables the terahertz detection. The
resonant excitation of the hole and electron
plasmonic oscillations results in a substantial
increase in the terahertz detector responsivity at
the signal frequency close to the plasma frequency
and its harmonics. Because of the transit-time
effects, the GPIN-FET response at the higher
plasmonic modes could be stronger than for thefundamental mode. Our estimates predict thedetector responsivity up to a few 105 V/W at room
temperature [4], much larger than for otherelectronic terahertz detectors, such as Schottky

diodes, p-n junctions, Si CMOS, and III-V and
III-N HEMTs. The obtained results were presented
at four conferences [C-1—C4]. Two of thosepresentations were invited talks [C-1,C-2]. The
success of our collaboration is well presented inour review paper [5]. Some results are highlighted
below in the short texts, Figures and Figure

We demonstrated that the nonlinearity due to the
Coulomb drag of quasi-equilibrium carriers byinjected ballistic carriers of lateral n+ -i-n-n+graphene field-effect transistors (GFETs) can beused for effective resonant detection of THz
radiation, moreover the plasmonic oscillations in a
GFET channel enables lead to a strong resonant
enhancement of the response [3]. Figure 1 shows
the structure of the graphene field-effect transistors(GFET). The positive dc voltage Vg forms then-region. Apart from the dc bias component V, thesource-drain voltage comprises the ac signal
component įVȦ (t) = įVȦ exp(-iȦt) produced byincident radiation of frequency Ȧ received by anantenna, where įVȦ is the component amplitude.
As a result, the net source-drain current J includes
the dc component J, the ac component įJȦ(including the fundamental and higher harmonics),
and the rectified component ǻJȦ.

As the resonant plasmonic detection dramaticallyincreases the sensitivity of the terahertz detectors,

p-i-n (GPIN) field-effect transistor (FET) structure[4]. In the proposed device, the gated p and nregions serve as the hole and electron reservoirs
and the terahertz resonant plasma cavities. The

condition (inset) when the bias voltage is applied
between the side (source/drain) contacts.

We calculated the plasmonic frequencies forseveral devices and the ac rectified component ǻJiȦand responsivity of the GPIN-FET. The rectified
current components, exhibit two pronounced
maxima (in the frequency range underconsideration, Ȱ /2 ȧ ӊ 4 THz). The firstmaximum corresponds to the signal frequency
close to the gated regions plasma frequency. It is
obviously related to the excitation (by the
incoming signal) of the fundamental mode of astanding plasma wave with the wave number q1 §ȧ/2L and the maximum amplitude at the ends ofthe i-region, x = ±l, having the opposite phases.
The collisional damping of these plasma
oscillations results in lowering of the plasma
resonance peaks. The second resonant peaks
correspond to the excitation of the plasmonic modewith the wave number q3 § 3ȧ/2L. It is instructivethat the peaks associated with this mode can behigher than those related to the fundamentalmode.

[2] ◊✲⤒㐣 (Summary)
The purpose of this collaborative project is to further expand ourprevious studies by investigating a range of interactions withsmartphone interfaces for several dominant in-VR tasks beyond
text typing. More specifically, we plan to (i) explore interaction
aspects on smartphone interfaces for the different possible
interactions in VR including, navigation, manipulation, selection,and (ii) evaluate the user experience and interaction performancecompared to other VR controllers and accordingly (iii) defineinteraction standards or guidelines for VR interactions using SIs.

Figure2: smartphone interfaces zones for locomotion. The user’s
finger should touch any location on the upper zone to move
forward (left smartphone) or any location on the lower zone tomove backward (rightThis year, PI and RIEC had frequent discussions over emails andvideo conference system. Specifically, we argued our researchplatform creation and another research funding application to
expand this project.
Then, we could successfully setup the research platform using a
HMD and smartphone using this project’s budget. The next goal
is to prepare software to achieve the research plan and that PI will
physically visit the RIEC to perform fine-tuning of the platform
and run user-study. We also successfully obtained anotherfunding (Daiwa Anglo-Japanese Foundation) that would
significantly expands this collaboration. It can be considered as aresult of this RIEC collaborative research project, and allows
Kazuki Takashima (RIEC collaborator) to visit Manchester toexpand the current project.

Setup the research platform by an HMD and a foldable
Android Smartphone
Prepare the initial software to run experiential system.
Formulate the further steps for the next two years.
Got a Research funding (DAIWA Anglo-Japanesefoundation) would deepen this collaboration from the next
year.

This collaborative research project will be continued next year byusing the same scheme of the RIEC Nation-wide Cooperative
Research Projects or other related project. The expected
outcomes of the project are twofold:
A. Fix the software to design various interactions using ourresearch setup.
B. Run an initial study to access our basic idea and design.
The future impact of this work will be significant specifically interms of establishing compact-mobile HMD setup that would be
more promising in office environment or transportation (e.g.,
airline) than the current setup with game-oriented hand-heldcontrollers. This work would contribute the new style of HMD
and office VR applications.

The Japanese concept/character MA (㛫), commonlytranslated as gap, interval, or the in between, partakes inmany forms of Japanese arts (e.g. architecture, tea ceremony,dance), sports (e.g. Japanese wrestling, fencing, martial arts), and daily
life practices (e.g. speaking, walking, to social interaction).
There is a recent calling to attend to the “interpersonal dimension ofMA”, and we intend to form an interdisciplinary research team toapply research techniques from psychology, neuroscience,engineering, and humanities to conceptualize and quantify this richcultural concept.
We proposed to understand MA is not as beingoutside, as an empty space or silence, but within us(individually and collectively), experienced as a certain
quality of attention or perceptual mode highlighting the
anticipation of action (a-tension). Our research group took
diverse approaches to connect this new endeavor with otherbetter established fields such as non-verbal communication,
computer-human interaction, and cultural influences onperception and cognition.

In this year, we have initiated group member
activities in person as well as remote collaborative methods.
We have organized 2 workshops together with invited talks
at Tohoku University.

Playback Theater Workshop: The
first Playback Theater Company was founded in 1975
by Jonathan Fox and Jo Salas. This theater is an originalform of improvisational theater in which participants
tell stories from their lives and watch them enacted on
the spot. There are varieties of forms in theatricalmethod and this workshop offered an introduction toparticipants. (Instructors: Miki Mushiake & HajimeMushiake)

Contact improvisation (CI) Workshop: CI is an improvisational
dance that establishes contacts and relationships with self andothers. Without words, our bodies deepen self-awareness andunderstanding of others effortlessly, possibly because the bodyperceives and conveys the essence of each other unconsciously.
We started with a careful warm-up to loosen up the body,followed by improvisational dancing and movements withothers. During the reflection time, we talked about what the body
experienced and what moved the mind. (Workshop Instructors:
Shoko Kashima & Chico Katsube (Contact Improvisation

We will use the foundation this year to seek forpossibilities of international event organization to increase
the awareness of our research theme and capacities. We are atruly interdisciplinary research team with a niche to study
cross-cultural and cross-boundary of various forms ofcommunication. Our goals are not limited to academic
excellence, but also to engage community participation inachieving more together.

This research aims at developing fundamental
technologies of edge computing and edge-assisted
smart systems for smart cities. The researchcollaboration was mainly carried out by having
workshops. Specifically, we organized and carriedout the following workshop:
1) Name: RIEC Workshop on Key Technologies
for Smart Cities
2) Date: 2022/2/22
3) Place: RIEC
4) Number of participants: 5
In this workshop, Prof. Go Hasegawa fromTohoku University presented his recent research
about packet scheduling algorithm between
wireless base stations and C-RAN, which areconnected with PON. This research is very
important for lowering the operational cost ofmobile carriers. Prof. Hiroshi Masui from Kitami
Institute of Technology presented the developmentof bus location system. With this system, bus
passages can obtain the real time location of thebuses they are waiting from smart phone
application. Prof. Guowei Lu from Aizu University
presented the latest research results about opticalcommunications, and Master student Hongyang
Hong from Kitami Institute of Technology
presented an approach to improve the effectivenessof renewable energy. All the presentations areclosely related to smart city. The participants had an
extensive and in-depth exchange of views. 㹙3㹛ᡂᯝ (Results)

This year, our focus is on smart energy schedulingtechnology for interconnected micro grids. For thispurpose,1) We conducted a comprehensive survey about
micro grids, and clarified both quantitative andqualitative requirements from micro grid users.
2) We built a comprehensive mathematical model tocatch the main characteristics of the energy schedulingproblem, defining the objective function, andclarifying the main constraints.
3) We proposed novel optimization algorithms withmulti-agent deep reinforcement learning to solve theoptimal scheduling problem. Fig. 1 shows that the
proposed method can save the energy cost
significantly
for
the
micro
grid
users.

In addition, we also developed a truthful auction
algorithm for trading edge resources, and a predictionbased routing algorithm for vehicle networks.

AI application in industry, business, medical treatment andhuman science is the most remarkable and forward-looking
research area. The proposed study area, AI in Human
Studies will create synergy based on the strength of the two
research institutes. The AI and advanced robotic center at
NTU consists of a strong team from human studies: education,
psychology, medicine, humanities, and etc. RIEC at Tohoku
includes experts in Advanced Acoustic Information Systems,
Visual Cognition and Systems, Interactive Content Design,

Soft Computing Integrated System, New Paradigm VLSI
System.
The two research institutes have co-organized a
symposium (The First NTU-Tohoku Symposium on
Interdisciplinary AI and Human Studies) on December 23,
2017 in Taipei, Taiwan. It was a public event which attracted
more than 100 attendants from academic fields and the public.
From the initial preparation and execution, the two teams
have established several possible collaboration research lines
as well as joint research plan. The second Tohoku-NTU
symposium was held on November 24 and 25, 2018 at RIEC
in Sendai , the third one was held on NTU, on November 24,
2019 and the fourth one and fifth one were held on March 12
and 13, 2021 and March 19th, 2022 on line due to the COVID
19 pandemic.
In this year, the sixth NTU-Tohoku Symposium on
Interdisciplinary AI and Human Studies was held on
February 26th. It had 16 talks and the tilts and speakers areshown below.

Cross-cultural Study Among Japanese, Russian andTaiwaneseAmong the topics listed above, details are shown for
topic (2) and (9).For the topic (9), a group of researchers
between two university estimated students’ mental states
while studying. While participants were solving alanguage puzzle, facial images were recorded. There
376

were several hints for the participants who clicked abutton to get one during the task. Analyzing facial
expressions succeeded predict the time when aparticipant required a hint. This indicates that Ai could
use facial images to provide hints at appropriate time inlearning processes.
For the topic (9), cultural differences in crossmodal color-taste associations were investigated among
Japanese, Taiwanese, and Russian respondents. The
participants were asked to choose a color from a 35-color
palette that corresponds to a particular item including
three voices (male, female, and child), five basic tastes,
five types of oral chemesthesis (hot, sharp, spicy, fatty,
and astringent), and eight functional foods. The results
demonstrate that cross-modal associations were mostly
similar among the participants. However, for somespecific tastes such as umami, more cultural differenceswere observed. The results indicate there are specificcultural features in addition to the common associations
between color and taste for participants from different
cultures.
