Visualizing Band Offsets and Edge States in Bilayer-Monolayer Transition Metal Dichalcogenides Lateral Heterojunction
Chendong Zhang, Yuxuan Chen, Jing-Kai Huang +5
Semiconductor heterostructures are fundamental building blocks for many important device applications. The emergence of two-dimensional semiconductors opens up a new realm for crea…
Direct Measurement of Exciton Valley Coherence in Monolayer WSe
Kai Hao, Galan Moody, Fengcheng Wu +7
In crystals, energy band extrema in momentum space can be identified by their valley index. The internal quantum degree of freedom associated with valley pseudospin indices can act…
Atomically Thin Resonant Tunnel Diodes built from Synthetic van der Waals Heterostructures
Yu-Chuan Lin, Ram Krishna Ghosh, Rafik Addou +10
Vertical integration of two-dimensional van der Waals materials is predicted to lead to novel electronic and optical properties not found in the constituent layers. Here, we presen…
