Assessment of valley coherence in a high-quality monolayer molybdenum diselenide
Yuto Urano, Xue Mengsong, Kenji Watanabe +2
We investigate the valley coherence in high and low-quality monolayer MoSe2 by polarization-resolved photoluminescence spectroscopy. The observed valley coherence is on the order o…
Gate-modulated reflectance spectroscopy for detecting excitonic species in two-dimensional semiconductors
Mengsong Xue, Kenji Watanabe, Takashi Taniguchi +1
We have developed a microspectroscopy technique for measuring gate-modulated reflectance to probe excitonic states in two-dimensional transition metal dichalcogenides. Successfully…
Two-dimensional atomic-scale ultrathin lateral heterostructures
Nanami Ichinose, Mina Maruyama, Takato Hotta +8
Ultrathin lateral heterostructures of monolayer MoS2 and WS2 have successfully been realized with the metal-organic chemical vapor deposition method. Atomic-resolution HAADF-STEM o…
Trion confinement in monolayer MoSe2 by carbon nanotube local gating
Takato Hotta, Haruna Nakajima, Shohei Chiashi +5
We have successfully confined trions into a one-dimensional restricted space of a MoSe2 device with CNT gate electrodes. The dry transfer process, including deterministic dry trans…
Interlayer interactions in one-dimensional van der Waals moiré superlattices
Sihan Zhao, Ryo Kitaura, Pilkyung Moon +2
Different atomistic registry between the layers forming the inner and outer nanotubes can form one-dimensional (1D) van der Waals (vdW) moiré superlattices. Unlike the two-dimensio…
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…
