Observation of a Mott quantum spin Hall insulator in twisted WSe2
Yifei Jin, Yaqi Ma, Aoqian Zhang +9
Quantum spin Hall (QSH) insulators and Mott insulators are conventionally regarded as distinct insulating phases, arising from band topology and strong Coulomb interactions, respec…
Light-induced percolative topological phase transition in type-II Weyl semimetal WTe2
Xiaoyue Zhou, Fu Deng, Yifan Gao +5
We report on an ultrafast terahertz free-carrier dynamic study of a photo-excited WTe2 thin film. In the photo-excited state, we observe a metastable electronic state featuring neg…
Unconventional ferroelectricity in half-filling states of antiparallel stacking of twisted WSe2
Liheng An, Zishu Zhou, Xuemeng Feng +9
Abstract: We report on emergence of an abnormal electronic polarization in twisted double bilayer WSe2 in antiparallel interface stacking geometry, where local centrosymmetry of at…
Bridging the gap between atomically thin semiconductors and metal leads
Xiangbin Cai, Zefei Wu, Xu Han +15
Electrically interfacing atomically thin transition metal dichalcogenide semiconductors (TMDSCs) with metal leads is challenging because of undesired interface barriers, which have…
Effects of Hexagonal Boron Nitride Encapsulation on the Electronic Structure of Few-layer MoS
Xu Han, Jiangxiazi Lin, Junwei Liu +2
The hexagonal boron nitride (hBN) encapsulation has been widely used in the electronics applications of 2D materials to improve device performance by protecting 2D materials agains…
