Stacking-order-dependent electronic properties of MoTe2/WSe2 moiré bilayers
Zhongdong Han, Wenjin Zhao, Eegene Clara Chung +17
Transition metal dichalcogenide (TMD) moiré bilayers have realized a wide range of strongly correlated and topological phenomena. The physics in these materials is often sensitive…
Evidence of topological Kondo insulating state in MoTe2/WSe2 moiré bilayers
Zhongdong Han, Yiyu Xia, Zhengchao Xia +6
Topological Kondo insulators (TKIs) are topologically protected insulating states induced not by single-particle band inversions, but by the Kondo interaction between itinerant ele…
Emergence of Chern metal in a moiré Kondo lattice
Wenjin Zhao, Zui Tao, Yichi Zhang +9
A Chern metal is a two-dimensional metallic state of matter carrying chiral edge states. It can emerge as a doped Chern insulator, but theoretical studies have also predicted its e…
Time-reversal symmetry breaking fractional quantum spin Hall insulator in moiré MoTe2
Kaifei Kang, Yichen Qiu, Bowen Shen +7
Twisted bilayer transition metal dichalcogenide semiconductors, which support flat Chern bands with enhanced interaction effects, realize a platform for fractional Chern insulators…
Correlated states controlled by tunable van Hove singularity in moiré WSe2
Patrick Knüppel, Jiacheng Zhu, Yiyu Xia +7
Twisted bilayers of transition metal dichalcogenide semiconductors have enabled the discovery of superconductivity, ferromagnetism, correlated insulators and a series of new topolo…
