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…
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…
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…
Size-Dependent Luminescence Properties of Chromatographically-Separated Graphene Quantum Dots
Naoto Fuyuno, Daichi Kozawa, Yuhei Miyauchi +6
We studied the photoluminescence (PL) properties of graphene quantum dots (GQDs) separated by size-exclusion high performance liquid chromatography. The size separation of GQDs was…
