Thin films from carbon nanotubes of highly tuned
structure and properties
Monday, 9 July 2018 18:45 (15 minutes)
Due to remarkable electrical, thermal, optical and other properties of carbon nanotubes they haveattracted significant interest from research groups all over the world. However, to implement
them in the real life, we still need better methods to control their structure at the nanoscale and also
techniques to turn these highly defined materials into macroscopic ensembles. In this contribution,
I will present results of our work how we have attempted to solve these problems. I will share ourrecent advances on the front of sorting CNTs by electrical character and chirality [1,2]. I will also
show a method developed by us, which enables formation of free-standing thin films from any typeof CNTs including that of monochiral nature [3,4]. The obtained materials are very promising fora wide range of electrical and optical applications.

Environmental electrometry with luminescentcarbon nanotubes
Wednesday, 11 July 2018 17:15 (15 minutes)
We demonstrate that localized excitons in luminescent carbon nanotubes can be utilized to study
electrostatic fluctuations in the nanotube environment with sensitivity down to the elementarycharge. By monitoring the temporal evolution of the cryogenic photoluminescence from individual carbon nanotubes grown on silicon oxide and hexagonal boron nitride we characterize thedynamics of charge trap defects for both dielectric supports. We find a one order of magnitude
reduction in the photoluminescence spectral wandering for nanotubes on extended atomically flat
terraces of hexagonal boron nitride. For nanotubes on hexagonal boron nitride with pronounced
spectral fluctuations our analysis suggest proximity to terrace ridges where charge fluctuators agglomerate to exhibit spatial densities exceeding those of silicon oxide. Our results establish carbon
nanotubes as sensitive probes of environmental charge fluctuations and highlight their potential
for applications in electrometric nanodevices with all-optical readout.

Cryogenic spectroscopy of sp3 defect states incarbon nanotubes
Monday, 9 July 2018 17:00 (15 minutes)
Photoactive defect states in semiconducting single-walled carbon nanotubes (CNTs) have the potential to enable novel applications in quantum photonic technologies. While early experiments
have established cryogenic CNTs as quantum light emitters [1], more recent work has identified luminescent defect states as sources of single photons up to room temperature [2,3]. For chemicallyengineered CNTs, sp3 functionalization offers means to deterministically influence the corresponding trap state properties via the characteristics of the covalent side chains. Recent findings showthat the incorporation of sp3 alkyl defects into the sp2 lattice of narrow-diameter CNTs promotes
the formation of both neutral and charged localized excitons [4] with unexpectedly high quantum
efficiency. Here, we report the results of our cryogenic photoluminescence studies carried out on
individual nanotubes functionalized with sp3 side-wall chemistry.

Photocurrent Spectroscopy of Dye Sensitized
Carbon Nanotubes
Wednesday, 11 July 2018 17:30 (15 minutes)
Monochiral (7,5) single walled carbon nanotubes (SWCNTs) are integrated into a field effect transistor device in which the built-in electric field at the nanotube:metal contact allows for exciton
separation under external light bias. Variable wavelength spectroscopy and 2D surface mappingof devices consisting of 10 –20 nanotubes is performed in the visible, and a strong correlation between the nanotube’s second optical transition (S22) and the photocurrent is found. Subsequently,
the SWCNTs are non-covalently modified with three different fluorescent dye molecules with offresonant absorption maxima at 532, 565, and 610 nm. Energy transfer from the dyes onto the
SWCNTs allows for the optical properties of the nanotube to be tailored and holds promise for thedevelopment of photo-detectors and for applications in photovoltaics and biosensing

Cavity-control of bright and dark interlayer excitonsin van der Waals heterostructures
Monday, 9 July 2018 17:45 (15 minutes)
Monolayer transition metal dichalcogenides integrated in optical microcavities host exciton-polaritons
as a hallmark of the strong light-matter coupling regime [1]. Analogous concepts for hybrid lightmatter systems employing spatially indirect excitons with a permanent electric dipole moment inheterobilayer crystals promise realizations of exciton-polariton gases and condensates with immanent dipolar interactions. Here, we identify optical signatures of spatially indirect momentumbright and momentum-dark interlayer excitons in vertical MoSe2 -WSe2 heterostructures and implement cavity-control of both exciton manifolds. To this end we employ a tunable open-accesscavity with one curved fiber-based mirror [2] and one planar mirror with extended MoSe2 -WSe2
heterobilayer flakes on top. The configuration of controlled intermirror spacing and lateral scanning capabilities is used to explore the light-matter coupling of excitons as a function of the cavity
length at representative positions of heterobilayers selected by two-dimensional cavity imaging.
Our experiments quantify the strength of interlayer excitons and demonstrate Purcell enhancement in cavity-modified photonic environments [3].

Direct Determination of Chemically Induced Doping
Concentrations in (6,5)- Single-Wall Carbon
Nanotubes by EPR
Thursday, 12 July 2018 10:00 (20 minutes)
Control over doping of semiconducting Single-Wall Carbon Nanotubes (SWNTs) by (electro-) chemical methods and intrinsic impurities are considered to be crucial for future applications of SWNTs
in carbon-based electronics and photonics. Previous indirect all-optical techniques hypothesize
charge carrier localization in semiconducting (6,5)-SWNTs following redox chemical AuCl3 doping, which is indicated by spectral and dynamical changes of the S1 exciton band [1].
Here, we present direct quantitative investigations of chemical impurities by means of electron
paramagnetic resonance (EPR). For the as-produced (6,5)-SWNT samples we detected very low
signal intensities stemming from two separate radical-like, isolated spin contributions that we assign to defects or residual impurities and which may be associated with what is sometimes referred
to as intrinsic p-doping. Their concentration indicates exceptional nanotube quality with only few
paramagnetic species per µm nanotube. Upon addition of the doping agent (AuCl3)2 we observea linear increase of the EPR signal intensity which we ascribe to localized p-type impurities on
the nanotube. However, at higher doping concentrations, the observed signal saturates, before decreasing again and finally vanishing at the highest AuCl3 concentrations. This seemingly puzzling
result can be understood in terms of the formation of EPR silent, diamagnetic bi-radicals whichstart to appear at moderate doping concentrations. We model this behaviour with a stochastic
formation of impurity sites in a 1D lattice, yielding good agreement with experimental data. In
conclusion, we can confirm charge carrier confinement at low impurity concentrations in SWNTs
with potentially far reaching implications for future device applications.

Spectral tuning of optical coupling between
air-mode nanobeam cavities and individual carbon
nanotubes
Wednesday, 11 July 2018 17:00 (15 minutes)
We design high quality factor air-mode nanobeam cavities by finite-difference time-domain simulations, and utilize the cavities to enhance the emission of air-suspended carbon nanotubes 1.
The cavities are fabricated from silicon-on-insulator wafers, and nanotubes are synthesized overthe cavities by chemical vapor deposition. Photoluminescence spectroscopy is performed on thedevices, where we observe optical coupling when the nanotube emission energy is close to thecavity resonance. Taking advantage of laser-heating-induced blueshifts of the nanotube emission,
we can reduce the detunings 2. We derive and numerically calculate the generalized expression
for the spectral overlap, and good correlation to the enhancement factors is obtained.

Nonperturbing, conjugation-preserving covalentfunctionalization of single-walled carbon nanotubes
Monday, 9 July 2018 11:40 (20 minutes)
The most common outcome of covalent treatments of carbon nanotubes is the conversion of sp2
carbon atoms into their sp3 hybridization state. Even mild approaches interrupt the conjugationof the carbon network with detrimental effects on their optoelectronic properties. Cycloaddition
reactions establish covalent bonds through pi-electrons to bridge targeted functionalities onto thetubes. The carbon atoms below the bridge are converted into the sp3 state (closed configuration,
Fig. 1a) or, if the C-C bond below the bridge is released, keep their sp2 character (open configuration, Fig. 1b) and preserve the overall conjugation of the extended network. We have recently
demonstrated that the outcome of a triazine-based [2+1] cycloaddition reaction results in the open
configuration (Fig. 1c) and preserves the intrinsic properties of the tubes, even at high degrees offunctionalization (4%) 1. Here we will highlight some of the benefits of this approach, such as thepreservation of their radiative emission (Fig. 1d) or the fine-tuning of the position of their Fermi
levels.
We will moreover discuss how the functionalized tubes can be exploited as starting platform for advanced materials. We show how the attachment of molecular systems makes them integrating partand in electronic communication with the conjugated network of the tubes, yielding new ways to
non-perturbatively tailor, control, and alter the optical response of the tubes for novel applications.
The conjugation of the molecular switch spyropiran-merocyanine, for example, enables controlled
on-off switching of the tubes’emission to be exploited for nanotubes-based super-resolution microscopy.

Killer defects in semiconducting SWNTs
Wednesday, 11 July 2018 14:00 (30 minutes)
The doping of semiconductors is key for providing electronic and photonic devices with their desired functionality. This comes with the realization, that the failure to successfully dope certainclasses of materials “is an important bottleneck for the technological utilization of these materials”
in electronic or photonic devices, as succinctly expressed by Zunger 1. This concern also pertains
to the doping of semiconducting single-wall carbon nanotubes (s-SWNTs) where our ability toprovide stable and measured concentrations of surplus carriers remains a major challenge.
Current approaches to doping of s-SWNTs are mostly designed around redox chemistry or covalentmodification with electron pulling or pushing side-chain functionalities while the use of substitutional impurities has hardly been explored for the purpose of electronic enhancement. Despite
the importance of doping for device technologies, however, it appears that our ability to quantify
the concentration of impurity site concentrations or their effectiveness in providing surplus free
carriers is still rather limited.
To address these shortcomings we have performed spectroscopic investigations of redox-and electrochemically doped (6,5) s-SWNT samples using fluorescence and absorption spectroscopy 2.
Spectroscopically, there appears to be no noticeable difference between these two approaches. In
both cases, exciton bands are found to broaden, become asymmetric and shift to higher energies
when the electrochemical potential is shifted toward valence or conduction band edges. These observations are consistent with confinement of excitons by a stochastic distribution of impurities,
suggesting that doping is in-homogeneous rather than homogeneous. Moreover, our analysis suggests that the interaction of minority carriers with external counterions can provide deep traps in
the band gap which act as ‘killer defects’, capturing free charge carriers and effectively preventing
the desired homogenous doping.
We also discuss how the analysis of exciton absorption bands can be applied to quantify impurity
level concentrations. In the context of optical spectroscopy this allows to define and clearly distinguish between intrinsic-, weak-, moderate- and heavy-doping regimes. The onset of degenerate
s-SWNT doping is determined to be at about ± 0.1 e/nm.
The observed generation of deep charge traps by adsorbed counterions can largely be attributed
to weak dielectric screening of Coulomb interactions by SWNTs or their environment, a common characteristic of low-dimensional systems. We take this as evidence for serious fundamental
challenges which may have far reaching and possibly broader implications for the successful fabrication of functional semiconductor devices from nanoscale materials.

Excitons in Coupled Nanotube Photovoltaic Thin
Films
Tuesday, 10 July 2018 11:10 (30 minutes)
We have previously reported on the efficient harvesting of excitons from photoexcited, semiconducting nanotube thin films. The films are interfaced with C60 fullerenes to form a type-II heterojunction with band offsets that exceed the exciton binding energy. Excitons photogenerated
near the heterointerface are dissociated into separable electrons (which transfer to C60) and holes(which remain on the nanotubes) with quantum efficiency ≈ 90%. This behavior has promise forcreating nanotube photoabsorber-based photovoltaic solar cells and photodetectors. However, theefficiency by which excitons can be dissociated remains high only when the nanotube films arethin (5 nm in thickness). The efficiency rapidly decreases as the nanotube film thickness increases,
due to poor inter-nanotube exciton migration.
Here, we present on recent work designed to understand and improve exciton migration in coupled nanotube films via theory 1 and experiments [2-4]. We have calculated exciton transfer rates
due to Coulomb coupling between nanotubes of varying orientations considering both first- andsecond-order (phonon-assisted) processes. Second-order dark-to-bright inter-nanotube transfer is
as fast as both first and second order bright-to-bright transfer. This important result shows thatdark excitonic states are able to efficiently and directly transfer between nanotubes in films.1 We
have tested the hypothesis that poor inter-nanotube exciton migration in films can be attributed
to quenching by defects via experiments in which (i) diazonium defects are intentionally added
to nanotubes at known concentrations 2 and in which (ii) nanotubes are prepared via three different processes of decreasing harshness: extended ultrasonication, brief ultrasonication, and shear
force mixing [3]. Inter-nanotube exciton transfer is then characterized via photoluminescence-,transient absorption-, and device photocurrent spectroscopies. Our results show that poor outof-plane exciton diffusion depth can be attributed in large part due to losses that arise from thetrapping and quenching of excitons by defects induced during processing. Other photovoltaic parameters including fill-factor and open-circuit voltage also improve with decreasing processing
harshness.

Carbon Nanotube Optical Bandgap Modulation forCancer Research and Diagnosis
Wednesday, 11 July 2018 10:40 (30 minutes)
The measurement of biomarkers, drugs, and metabolites in live cells and organisms would allow for
improvements in disease detection, drug development, and biomedical research. Single-walled carbon nanotubes have suitable optical properties for application as sensors for use in live cells and invivo, including narrow, near-infrared emission bands with sensitivity to the local environment. To
develop them into sensors for bioanalytes, we devised new methods to probe single-walled carbon
nanotube optical properties, including near-infrared hyperspectral imaging and live-tissue excitation/emission spectroscopy. We also identified a new mechanism of carbon nanotube photoluminescence environmental responsivity, whereby electrostatic charges mediate spectral red-shifting.
We believe that this effect is consistent with previous findings of carbon nanotube solvatochromic
behavior. We found that this mechanism facilitates the measurement of multiple classes of bioanaltytes, such as nucleic acids, drugs, and proteins, enabling the development of in vivo implantablesensors for the study and detection of cancer.

Transition metal dichalcogenide nanotubes
Wednesday, 11 July 2018 09:00 (30 minutes)
Due to their favorable and rich electronic and optical properties, group-VI-B transition-metal
dichalcogenides (TMDs) have attracted considerable interest. They have earned their positionin the materials portfolio of the spintronics and valleytronics communities. The electrical performance of TMDs will be enhanced by rolling up the two-dimensional (2D) sheets to form quasi-onedimensional (1D) tubular structures. Actually, the TMD nanotubes were first synthesized back in
1992 1, but only recently device related researches have been conducted 2.In this presentation, we
discuss transport and optoelectronic properties ranging from field effect transistor (FET) operation
to solar cell actions in tungsten disulfide multiwalled nanotubes (WS2-NT).
We first fabricated electric double layer transistor (EDLT) of an individual WS2-NT and found an
ambipolar operation, in sharp contrast to the solid gated FET devices which exhibits only n-typeconduction. Furthermore, we found that gating with KClO4/polyethylene glycol electrolyte, induce superconductivity at Tc = 5.8 K. This is the first superconductivity in the individual nanotube
structure. Importantly, this superconductivity of gated WS2 exhibited peculiar transport properties arising only from tublar and chiral structure [3].
Using the EDLT devices, we were able to fabricate a p-n junction in an individual WS2-NT, andfound that this p-n junction shows current-driven light emission, and photovoltaic actions. Bothof these actions are linearly polarized along the NT axis, and more importantly, the external quantum efficiency for the photovoltaic effect reaches a value as high as 4.8%, exceeding by far that of
2D TMDs and even approaching the internal quantum efficiency of the 2D TMDs [4].

Room-temperature single photon emission fromcarbon nanotubes
Monday, 9 July 2018 16:40 (20 minutes)
Single-walled carbon nanotubes are a promising material as quantum light sources at room temperature and as nanoscale light sources for integrated photonic circuits on silicon. Here we discuss
the use of carbon nanotubes as room-temperature single photon emitters from two different approaches. The first is where efficient exciton-exciton annihilation process 1 is used to reduce thenumber of mobile excitons. We investigate photon statistics in as-grown individual air-suspended
carbon nanotubes and perform theoretical analysis to show that diffusion-driven annihilation ofmobile excitons can produce high-purity single photons 2. In the second approach where exciton
trapping sites are created to localize excitons [3], we demonstrate integration of carbon nanotube
dopant states to silicon photonic crystal microcavities [4]. The coupling of the dopant emission to
the microcavity results in an increase of photoluminescence by a factor of ~100, corresponding toa single-photon emission rate of 1.7 x 10^7 Hz which is the highest reported for room-temperature
operation of nanotube single photon sources. Our results show that both diffusive (1D) and localized (0D) excitons in carbon nanotubes can produce high quality single photons at room temperature, opening up a pathway to quantum light sources with additional functionality and flexibility.

Reflectance of Carbon Nanotube Forest
metamaterials
Wednesday, 11 July 2018 18:30 (15 minutes)
CNT forest of high emissivity, nearly ideal “black-body absorber1”, is attracting researchers as
a candidate material for the future application of high-sensitive sensor, thermal energy storage
device2, and so on. Recently, metamaterials, electro-magnetic circuit to the incident EM-wave,
opened a method to design desired optical properties. We recently reported CNT forest metamaterial in infrared and visible region in order to increase optical and thermal absorbance utilizing
FIB nanofabrication [3, 4].
In this paper, metamaterials composed by 1D anisotropic refractive index material of CNT Forests,
and the effect of nano-sized patterning on the optical and thermal properties are discussed. Figure
1 shows calculated UV-Vis-IR spectra of vertical- and parallel-aligned metal-nanorod CNT forests
to the Electric field (Ez) of incident EM wave, showing good correspondence to the experimental
results[5] shown in Fig. 1(d-g). Components of perpendicularly aligned CNTs, which were parallelto the Ez of EM wave, increased reflectance in longer wave length region. Alignment of CNTs had
an important role to improve absorption on the metamaterial patterns. Patterning shape effect of
CNT forest metamaterials[3-5] will be also discussed in detail.

Electrically generated light emission from carbon nanotubes is of great interest for the development of nanoscale on-chip electro-optical transducers and single-photon sources [1,2], operatingin the telecom band and at GHz frequency [3]. To further advance device performance, reproducibility and reliability we need to better understand and control the mechanism of light generation, tailor the interface between the nanotube and environment and to locally modify nanotube
properties with nanoscale precision. In my presentation I will report on our current efforts in thisdirection and present latest results.

Wednesday, 11 July 2018 18:45 (15 minutes)
Photoluminescence (PL) spectroscopy is one of the important analysis techniques for the opticalproperties of single-walled carbon nanotubes (SWNTs). However, PL spectra are measured only
from surfactant-wrapped SWNTs 1, suspended SWNTs 2, and vertically-aligned SWNTs [3]. For
optical and opto-electronic applications of SWNTs, SWNTs which lie on substrates and emit PL signal are needed. In this study, SWNTs were directly synthesized on hexagonal boron nitride (h-BN)
substrates and PL spectroscopy was performed. h-BN is a suitable substrate for SWNTs because it
has large band gap and its surface is atomically flat [4]. By using mechanical exfoliation technique,multilayered h-BN was obtained on silicon substrates. Iron metal particles and ethanol were usedas the catalyst and carbon source of SWNT growth, respectively. Figure 1 shows (A) PL spectrumand (B) PL map obtained from SWNTs on h-BN. Relatively sharp PL emission was measured. It is
known that the optical transition energy (Eii) of SWNTs depends on the surrounding conditions.
The E11 and E22 of SWNTs on h-BN were almost the same as those of surfactant-wrapped SWNTs,and PL map, as shown in Fig. 1(B), exhibited that the chirality was (9,5).

Long-lived Charge Separation Across Interfaces with
Semiconducting Single-walled Carbon Nanotubes
Thursday, 12 July 2018 10:40 (30 minutes)
Semiconducting single-walled carbon nanotubes (s-SWCNTs) are attractive absorbers for use insolar energy harvesting schemes because of their strong and energetically tunable optical absorption, and high charge carrier mobilities due to the delocalized nature of the π-electron system.
Beyond their technological potential, s-SWCNTs offer attractive properties for fundamental studies of charge generation in strongly confined nanoscale systems and photoinduced electron transfer (PET) processes. For example, strong quantum confinement and low dielectric screening impart single-walled carbon nanotubes with exciton-binding energies substantially exceeding kBTat room temperature. Additionally, the energetically narrow and distinct spectroscopic signatures
for excitons and charges within s-SWCNT thin films enables the unambiguous temporal tracking of fundamental photophysical processes occuring at important photoactive heterojunctions
designed for charge separation.
In this presentation, I will discuss recent studies that probe the generation and recombinationof long-lived charges in samples consisting of heterojunctions between s-SWCNTs and various
electron acceptors, both organic and inorganic. I will focus on the roles of important interfacial
properties that can influence the kinetics and efficiency of the interfacial PET process and recombination of the resulting separated charges. These properties include the energetic energetic driving
force for exciton dissociation, the amount of residual wrapping polymer on the highly enricheds-SWCNTs, the local dielectric enrivonrment, the presence or absence of an electric field, and geometrical factors of the interface that can be modified via structural properties of the acceptors.
Better fundamental understanding of these model interfaces can inform the design of more efficient solar energy harvesting systems, photodetectors, and other opto-electronic devices.

Optical properties of dyes confined into carbon andboron nitride nanotubes
Wednesday, 11 July 2018 15:40 (30 minutes)
The inner cavity of nanotubes has been used as a template for the encapsulation of elongateddyes molecules, such as polythiophenes (6T). The 1D confinement of the nanotube wall drives
the stacking of the molecules and induces original aggregation effects in their optical properties[1,2]. When confined inside a carbon nanotube, the organics dyes exhibit for instance a surprisingly strong Raman signal clear of its luminescence emission due to an efficiently quenching effectfrom the nanotube [3]. Here we show that boron nitride nanotubes (Eg~5 eV) having inner diameters between 1 nm to 5 nm provide similar 1D confinement effects with the difference that theypreserve the luminescence of the dyes. The resulting 1D nanohybrids (dye@BNNT) shows in photoluminescence imaging experiments strong and tunable luminescence emissions depending on
the dyes used. Experiments on individual dyes@BNNT demonstrate that the BNNT protect thedyes against oxidation and reduce significantly the dyes photobleaching under continuous photoexcitation. Preliminary results on Daphnia Pulex colored with dyes@BNNT suggest that thesedye@BNNT nanoprobes have reduced toxicity for multimodal imaging based on Raman and luminescence and that they can be adapted to work in the NIR I window to study biological materials.

Resonance Raman Signature of Intertube Excitons in
Compositionally-Defined Carbon Nanotube Bundles
Wednesday, 11 July 2018 18:45 (15 minutes)
Electronic interactions in low-dimensional nanomaterial heterostructures can lead to novel optical responses arising from exciton delocalization over the constituent materials. Similar phenomena have been suggested to arise between closely interacting semiconducting carbon nanotubesof identical structure. Such behavior in carbon nanotubes has potential to generate new exciton physics, impact exciton transport mechanisms in nanotube networks, and place nanotubes
as one-dimensional models for such behaviors in systems of higher dimensionality. Here we use
resonance Raman spectroscopy to probe intertube interactions in (6,5) chirality-enriched bundles.
Raman excitation profiles for the radial breathing mode and G-mode display a previously unobserved sharp resonance feature. We show the feature is evidence for creation of intertube excitons
and is identified as a Fano resonance arising from the interaction between intratube and intertube
excitons.1 The universality of the model suggests that similar Raman excitation profile features
may be observed for interlayer exciton resonances in 2D multilayered systems.

Achieving 20% Efficiency Perovskite Solar Cells withHigh Stability by using Semiconducting
Single-walled Carbon Nanotube Grain Bridges
Wednesday, 11 July 2018 18:45 (15 minutes)
Since liquid-junction perovskite solar cells (PSCs), the development of organo-lead halide perovskite photovoltaics research has gained momentum with the achievement of the solid-state PSCs
in 2012. High absorption coefficient, long-range diffusion length and high defect tolerance of
PSCs enable remarkable certified power conversion efficiencies (PCEs) over 20%. Although PSCs
are proven to be promising next-generation solar devices, further breakthroughs in terms of efficiency and stability are necessary to supersede conventional silicon solar cells. With regard to
the performance and stability of PSCs, perovskite grain boundaries play a significant role. Structural disorders at these boundaries induce shallow trap states and non-radiative recombination of
localised charge carriers which serve as limitations to PSC performance. At the same time, theseareas are also responsible for the perovskite degradation, as the reaction with moisture in air has
been found to initiate from the grain boundaries. Therefore, technologies aiming at passivating
the perovskite grains are highly desired.
Over the last two decades, carbon nanotubes (CNTs) with an exceptional charge carrier property
with outstanding chemical and mechanical stability have generated a lot of excitement among
researchers for their device applicability. Especially, single-walled carbon nanotubes (SWNTs)
with a certain chirality possess a wide range of direct bandgap of up to 2 eV, qualifying for a lightharvesting medium with strong absorption and high carrier mobility. Semiconducting SWNTs(s-SWNTs) are highly conductive along the tube axis and therefore can function effectively asa charge-transporter between perovskite grains. While there have been a few reports on phenylC61-butyric acid methyl ester (PCBM) as a charge-transporter at the grain boundaries of perovskite
films, fullerenes have inherently low carrier mobility and low stability compared to SWNTs. It has
also been demonstrated that hydrophobic and air-stable SWNTs can protect the perovskite layer
successfully from the oxygen and moisture.
Here, we fabricated PSCs in a configuration of glass/ITO/SnO2/CH3NH3PbI3/spiro-MeOTAD/Au
in which the perovskite grains are passivated and connected by s-SWNTs. s-SWNTs here arefunctioning as a charge-transporter, light-harvester, and protector from the moisture in air. By
incorporating a small amount of s-SWNTs in deionised water, 18.0% efficiency of the reference
PSCs increased to 20% with reduced hysteresis. due to the increased perovskite grain size arisingfrom favourable vapour pressure of the solvent. Upon addition of s-SWNTs, the PCE further increased beyond 20% with improved hysteresis and air/light stability. Ultimately, s-SWNTs added
PSCs showed superior stability over the reference devices.

Effects of Chirality and Defect Introduction on theIntermediate Frequency Mode
Wednesday, 11 July 2018 18:45 (15 minutes)
An intermediate frequency mode (IFM) of single-walled carbon nanotubes (SWCNTs) has intriguing properties. The IFM originates from a phonon branch that has acoustic nature in graphene,
and has non-zero momentum. Phonons with these properties are usually not analyzable with photons. However, the IFM of SWCNTs was successfully observed in prior reports [1, 2]. Remarkablefeatures of the IFM may provide new insights into Raman spectroscopy of SWCNTs. Although
the effects of chirality and defect density on the peak position was well explained in these reports,
what determines the IFM intensity is not clear. We will show our recent analysis of the IFM intensity with focusing on the effects of chirality and defect density.
Intensities of the IFM, the D-mode, and the G-mode are shown in Figure 1a as functions of a duration time of defects introduction into an air-suspended SWCNT. Defects were introduced byusing photoinduced bleaching in air [3]. The G-mode intensity decreased as results of the defectintroduction. On the other hand, the IFM intensity increased along with the D-mode intensity.
Furthermore, fluctuations of the IFM intensity was clearly following that of the D-mode intensity,
which implies that the IFM originates from K-momentum phonons similar to the D-mode. From
the results shown in Figure 1a, we suggest the intensity ratio IIFM/ID as a good representation tounderstand the physics underlying K-momentum phonons. Figure 1b shows effects of chirality on
the IIFM/ID, as well as IRBM/IG, obtained from 5 kinds of SWCNTs; (12,1), (11,3), (10,5), (9,7), and(9,8). Although the chiral angle dependence of the IIFM/ID is less significant than the IRBM/IG,
the ratios decrease with an increase of the chiral angle.
