Effect of incoherent electron-hole pairs on high harmonic generation in an atomically thin semiconductor
Kohei Nagai, Kento Uchida, Satoshi Kusaba +3
High harmonic generation (HHG) in solids reflects the underlying nonperturbative nonlinear dynamics of electrons in a strong light field and is a powerful tool for ultrafast spectr…
A Versatile Post-Doping Towards Two-Dimensional Semiconductors
Y. Murai, S. Zhang, T. Hotta +13
We have developed a simple and straightforward way to realize controlled post-doping towards 2D transition metal dichalcogenides (TMDs). The key idea is to use low-kinetic energy d…
Efficient Growth and Characterization of One Dimensional Transition Metal Tellurides Inside Carbon Nanotubes
Naoyuki Kanda, Yusuke Nakanishi, Dan Liu +5
Atomically thin one dimensional (1D) van der Waals wires of transition metal monochalocogenides (TMMs) have been anticipated as promising building blocks for integrated nanoelectro…
Control of high-harmonic generation by tuning the electronic structure and carrier injection
Hiroyuki Nishidome, Kohei Nagai, Kento Uchida +4
High-harmonic generation (HHG), which is generation of multiple optical harmonic light, is an unconventional nonlinear optical phenomenon beyond perturbation regime. HHG, which was…
Dynamical symmetry of strongly light-driven electronic system in crystalline solids
Kohei Nagai, Kento Uchida, Naotaka Yoshikawa +3
The Floquet state, which is a periodically and intensely light driven quantum state in solids, has been attracting attention as a novel state that is coherently controllable on an…
Monolayer MoS2 field effect transistor with low Schottky barrier height with ferromagnetic metal contacts
Sachin Gupta, F. Rortais, R. Ohshima +4
Two-dimensional MoS2 has emerged as promising material for nanoelectronics and spintronics due to its exotic properties. However, high contact resistance at metal semiconductor MoS…
Indirect bandgap of hBN-encapsulated monolayer MoS2
Yosuke Uchiyama, Kenji Watanabe, Takashi Taniguchi +5
We present measurements of temperature dependence of photoluminescence intensity from monolayer MoS2 encapsulated by hexagonal boron nitride (hBN) flakes. The obtained temperature…
Interband resonant high-harmonic generation by valley polarized electron-hole pairs
Naotaka Yoshikawa, Kohei Nagai, Kento Uchida +4
We demonstrated nonperturbative high harmonics induced by intense mid-infrared light up to 18th order that well exceed the material bandgap in monolayer transition metal dichalcoge…
The Atomic and Electronic structure of 0° and 60° grain boundaries in MoS2
Terunobu Nakanishi, Shoji Yoshida, Kota Murase +8
We have investigated atomic and electronic structure of grain boundaries in monolayer MoS2, where relative angles between two different grains are 0 and 60 degree. The grain bounda…
One-dimensional van der Waals heterostructures
Rong Xiang, Taiki Inoue, Yongjia Zheng +23
Property by design is one appealing idea in material synthesis but hard to achieve in practice. A recent successful example is the demonstration of van der Waals (vdW) heterostruct…
Intertube effects on one-dimensional correlated state of metallic single-wall carbon nanotubes probed by 13C NMR
Noboru Serita, Yusuke Nakai, Kazuyuki Matsuda +4
The electronic states in isolated single-wall carbon nanotubes (SWCNTs) have been considered as an ideal realization of a Tomonaga-Luttinger liquid (TLL). However, it remains uncle…
Observation of the intrinsic magnetic susceptibility of highly purified single-wall carbon nanotubes
Yusuke Nakai, Ryo Tsukada, Yasumitsu Miyata +3
We report the observation of the intrinsic magnetic susceptibility of highly purified SWCNT samples prepared by a combination of acid treatment and density gradient ultracentrifuga…
