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…
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…
Enhanced exciton-exciton collisions in an ultra-flat monolayer MoSe2 prepared through deterministic flattening
T. Hotta, A. Ueda, S. Higuchi +7
Squeezing bubbles and impurities out of interlayer spaces by applying force through a few-layer graphene capping layer leads to van der Waals heterostructures with ultra-flat struc…
Exciton diffusion in a hBN-encapsulated monolayer MoSe2
T. Hotta, S. Higuchi, A. Ueda +7
Excitons, quasi particles composed of an electron and a hole, play an important role in optical responses in low-dimensional nanostructures. In this work, we have investigated exci…
