Ultrafast carriers' separation imaging in WS2-WSe2 in plane heterojunction by transient reflectivity microscopy
Yangguang Zhong, Shuai Yue, Huawei Liu +4
Carrier transport in nanodevices plays a crucial role in determining their functionality. In the post-Moore era, the behavior of carriers near surface or interface domains the func…
Correlation-induced symmetry-broken states in large-angle twisted bilayer graphene on MoS2
Kaihui Li, Long-Jing Yin, Chenglong Che +6
Strongly correlated states are commonly emerged in twisted bilayer graphene (TBG) with magic-angle, where the electron-electron (e-e) interaction U becomes prominent relative to th…
Non-Equilibrium First-Order Exciton Mott Transition at Monolayer Lateral Heterojunctions Visualized by Ultrafast Microscopy
Long Yuan, Biyuan Zheng, Qiuchen Zhao +7
Atomically precise lateral heterojunctions based on transition metal dichalcogenides provide a new platform for exploring exciton Mott transition in one-dimension. To investigate t…
Electrically switchable valley polarization, spin/valley filter, and valve effects in transition-metal dichalcogenide monolayers interfaced with two-dimensional ferromagnetic semiconductors
Ao Zhang, Kaike Yang, Yun Zhang +2
Electron valleys in transition-metal dichalcogenide monolayers drive novel physics and allow designing multifunctional architectures for applications. We propose to manipulate the…
Indirect to direct band gap crossover in two-dimensional WS2(1-x)Se2x alloys
Cyrine Ernandes, Lama Khalil, Hela Almabrouk +12
In atomically thin transition metal dichalcogenide semiconductors, there is a crossover from indirect to direct bandgap as the thickness drops to one monolayer, which comes with a…
Magneto-spectroscopy of exciton Rydberg states in a CVD grown WSe2 monolayer
A. Delhomme, G. Butseraen, B. Zheng +9
The results of magneto-optical spectroscopy investigations of excitons in a CVD grown monolayer of WSe2 encapsulated in hexagonal boron nitride are presented. The emission linewidt…
