FORWARD
This research report is issued annually to summarize the research activities in the
Optoelectronic Device System Research and Development (OEDS R&D) Center, Kanazawa
Institute of Technology (KIT). This report, which covers the activities in the OEDS R&D
Center from April 2021 to March 2022, is distributed to researchers engaged in the study ofmaterials, devices and systems in the field of electronics, especially optoelectronics, in orderto stimulate mutual exchange of scientific information. We believe that this report represents
our continuing commitment toward achieving and maintaining research excellence in the areaof materials, devices and systems for optoelectronics.
Historically, the Electron Device System (EDS) Research Laboratory was established at
KIT in June 1984. Professor Ichiro Fukuda was installed as the first director of the EDS
Research Laboratory. Since the establishment of the EDS Research Laboratory, research has
centered on fundamental studies of materials, devices and systems as well as on technology tointegrate them into electronic devices. In the past 15 years, optoelectronic device system
research has grown into a major research field. For the purpose of focusing on thedevelopment of optoelectronic device systems, the EDS Research Laboratory wastransformed into the OEDS R&D Center attached to KIT in May 2000 with a regrouping of
the staff and construction of a new building (building 40). The OEDS R&D Center was
financially supported in part by a High-Tech Research Center Project Grant from the Ministryof Education, Culture, Sports, Science and Technology of Japan, and Professor Tadatsugu
Minami was appointed the first director of the OEDS R&D Center. There are two importantresearch projects in the OEDS R&D Center: the development of 1) Oxide Electronics and 2)
Next Generation Electronic Display Systems. We are extensively investigating new n- andp-type oxide semiconductors for optoelectronic devices, new oxide phosphors for emissive
displays, new optoelectronic devices and new display systems. These research projects weresuccessfully finished in March 2008.
After that, we have jointed a new research project in the Center for Electric, Optic andEnergy Applications attached to KIT and started in April 2011: Research and development of
optoelectronic device systems. A part of our works was financially supported by a Program
for the Strategic Research Foundation at Private Universities from the Ministry of Education,
Culture, Sports, Science and Technology of Japan. In 2017, Professor Minami, who served as
director for a long term since the establishment of the center, retired from the position of
director, and Professor Atsushi A. Yamaguchi has taken over the position.
All of us at the OEDS R&D Center are grateful for the generosity and continuing supportof the organizations and companies which have been providing research funds.

山口研究室 (Yamaguchi Laboratory)
Optical Properties of III-nitride materials and devices are investigated both experimentallyand theoretically. The following two topics are intensively being studied at present.
[1] Optical Gain Characteristics of InGaN Green-Emitting Laser Diodes
We theoretically predicted in 2006 that the utilization of semi polar GaN substrates isbeneficial to realize high-performance and low-cost green laser diodes. Now, we are
performing more realistic calculation of optical gain characteristics to design the device
structure in detail. In addition, experimental studies have just been launched to measure theanisotropic optical gain characteristics of semipolar-oriented InGaN quantum wells.
[2] Optical Characterization of GaN Substrates for High-Efficient White LEDs
High quality GaN substrates with low defect density and small residual strain are requiredfor high-efficient white LEDs. We are measuring time-resolved photoluminescence spectra toelucidate defect density and to investigate carrier dynamics. 2D-strain mapping measurements
by low-temperature micro-reflectance are also being carried out to understand the strain
relaxation mechanism and to reduce the residual strain in the substrates.

平間研究室 (Hirama Laboratory)［1］New SPA based (wasabi) plant factory with optimally controlled cultivation environment
utilizing the leaf electric potential
For plants that are considered difficult to grow in plant factories (wasabi), a controlled
cultivation environment that was created with IoT based sensor and actuator networks andcloud management was implemented early on.
By analyzing the weak leaf electric potentials from the wasabi when exposed to external
environmental stimuli, a “health check” on the wasabi is performed. In addition to growthenvironmental control based on other biometric SPA (Speaking Plant Approach) measurement
techniques, continuous health monitoring of the wasabi using the leaf electric potential data isalso obtained in order to further optimize the cultivation environmental control.
[2] Small scale low magnetic field MRI device development
In this laboratory, a low magnetic field small scale MRI device is under development. It is
intended to be used for medical diagnostics immediately after brain surgery. This high quality
light weight MRI system is being implemented in collaboration with the Applied Electronics
laboratory (AEL) using technology and techniques developed at KIT.

In addition, a low magnetic field 52mT MRI system is also being developed mainly toanalyze the internal makeup of food by measuring the relaxation time from MR images.
[3] Small scale high sensitivity FGM development
A small sized magnetic sensor (Fluxgate Magnetometer: FGM) with highly sensitive
magnetic saturation characteristics that can operate at room temperature was developed. Up
until now, an ultra-high sensitivity of 30pT/√Hz was achieved. The focus of the research fromnow is to rebuild and reduce the size of the sensor body while simplifying the magnetic
detection circuit.

宮田研究室 (Miyata Laboratories)
We are extensively investigating new n- and p-type oxide semiconductors for
optoelectronic devices, new oxide phosphors for emissive displays, new optoelectronic
devices and new display systems. A new research project was started in May 2007:
Development of indium substitute materials for a transparent conducting electrode. This
research was financially supported in part by the Rare Metal Substitute Materials
Development Project initiated by the Ministry of Economy, Trade and Industry of Japan andtransferred to the New Energy Development Organization from April 2008; the research
project was completed successfully in March 2009. A new research project was started inAugust 2010: Development of low cost and high quality transparent conducting oxide (TCO)
films by sputtering deposition. The research was financially supported in part by the New
Energy and Industrial Technology Development Organization (NEDO), Japan, via the
Photovoltaic Power Generation Technology Research Association (PVTEC), Japan; theresearch project was finished successfully in March 2013.
[1] Preparation and device application of intelligent oxide thin films.
Highly conductive and transparent thin films have many applications such as transparent
electrodes for optoelectronic devices and transparent heat mirrors for solar energy utilization.
Although indium tin oxide (ITO) films are in practical use, ITO is a relatively expensive
material because indium is in rather limited supply. We have proposed use of new transparent
conducting oxide (TCO) materials, consisting of ZnO and multicomponent oxide. Especially,
the following subjects are in progress:
1) Development of new TCO materials and its deposition techniques.
2) Development of new p-type oxide semiconductors and its deposition technique.
3) Development of optoelectronic devices using new oxide semiconductors.
4) Development of sensor and MEMS using new oxide semiconductors.
[2] Photovoltaic application of oxide semiconductors.

−5−We have proposed new p–n heterojunction solar cells have been fabricated using cuprous
oxide (Cu2O), a semiconductor with a direct energy gap of 2.1 eV. The significantly enhanced
efficiencies could be achieved in Al-doped ZnO (AZO)/n-type semiconductor/p-type Cu2O
heterojunction solar cells fabricated by preparing an oxide semiconductor thin film on athermally oxidized p-Cu2O sheet using low-damage and low-temperature deposition
techniques. The following subjects are in progress:
1) Development of new oxide semiconductor thin films materials as an n-type layer and its
deposition techniques.
2) The Cu2O homojunction was formed by epitaxially growing an impurity-doped Cu2O thinfilm on thermally oxidized polycrystalline p-type sodium-doped Cu2O sheets byelectrochemical deposition (ECD) method.

横谷研究室 (Yokotani Laboratory)
We have promoted researches of the Internet of Things (IoT) and related subjects by two
approaches, i.e., vertical and horizontal approaches.
[1] Researches by the vertical approach
We focus specific applications with IoT technologies. Then, we recognize social problems
and requirements, proposes solutions, and verify effectiveness of their solutions by several
methods, e.g., prototyping, computer simulation and mathematical analysis. We list
applications and their research activities as follows.
(1) Building Automation and Control System (BACS) as a cyber physical system
The Internet technologies have been applied to BACS for enhancement of connectivity ofvarious devices and cost reduction. However, in this situation, the threat of cyber-attack is oneof major concerns. Generally, this threat causes to damage physical facilities. We intend toevaluate a threat by traffic analysis on computer simulation and inferences of this threat on
hardware emulation.
(2) Surveillance system by using poles
Electric poles have been deployed widely along reads. We intend to configure distributed
basement for some applications using these poles. One of typical applications is thesurveillance system on roads. We deploy this system using poles with surveillance cameras byvideo signal processing, AI, and network technologies. We evaluate this system and someembedded algorithms in this system in the experimental station of KIT Hakusan mountaincampus.
In addition to these applications, we have investigated some applications, e.g., wildlife
monitoring and factory monitoring.

−6−[2] Researches by the horizontal approach
We have promoted R&D and standardization of IoT platforms focusing on network
technologies. We have focused on two type platforms, i.e., the access network platform andservice network platform as follows.
(1) Access network platform
In IoT applications, a number of end devices transfers tiny data blocks with highfrequency. Some applications require low latency communication. In this situation, seamless
communication between end points should be deployed for various IoT applications. We
propose traffic control mechanisms with cooperation between optical networks and 5G
networks. Especially, we propose active traffic control mechanisms with real time trafficmonitoring. We also verify their control mechanisms by mathematical analysis and computer
simulations.
(2) Service network platform
The current Internet does not seem to be suitable architecture for most of IoT applications,because the Internet causes large protocol overhead and heavy processing resources totransfer tiny data blocks in IoT applications. Therefore, we propose that the Information
Centric Network (ICN) technologies are applied to communication for IoT applications. ICN
does not require IP base routing and provides simplified communication sequences. We
research the IoT platform as the service network platform using ICN and emerging
technologies for this platform. Moreover, we promote standardization of this platform. We
contribute standardization of the IoT Data Exchange Platform (IoT-DEP), ISO/IEC 30161
series standardized by ISO/IEC JTC1/SC41.

深田研究室 (Fukada Laboratory)[1] Development of thin film phosphor materials
Our objective is the development of thin film phosphors with high efficiency and chemical
stability for inorganic thin-film electroluminescence devices and white light-emitting diodes.
Various phosphor thin films are prepared by a sol-gel dip coating followed by post annealing
at a high temperature. In addition, we will conduct studies on inorganic-organic hybrid
phosphors and luminescent devices utilizing these phosphors.
[2] First-principles molecular-dynamics calculations
The first-principles molecular-dynamics simulation is an effective method of explaining
and predicting various properties of semiconductors and metals though electron-statecalculations based on quantum dynamics. Aiming at the improvement of the experimental
conditions in the preparation of inorganic or organic semiconductors and/or the developmentof new optoelectronic devices, we will conduct exploring and predicting physical phenomenaon the atomic and electronic levels.

柳橋研究室 (Yanagibashi Laboratory)[1] Development of SPA typed mushroom factory
The final goal of our study is actual operation of SPA (Speaking Plant Approach) typed
mushroom factory. SPA means environmental control using some biological information as
index. In this study, bioelectric potential responses of mushrooms to various environmental
factors have been measured and associated with their morphogenetic properties. Mushroom
growth promotion by bioelectric potential activation has also been tried and it is gradually
becoming clear that bioelectric potential is effective as an index of growth control.
[2] Contactless measurement of plant physiological activity using magnetic fluid
This study is the world’s first trial aiming to realize a quite new method to measure plant
physiological activity without physical contact of sensors. It is considered that nano particle
sized magnetic fluid is absorbed into the plant body and its movement by solution transport
related to plant physiological activity will result in extremely weak magnetic fluctuations that
seems to be detectable without contact by FGM. In the future, we will also work on theapplication of this measurement technology on medical scene.
