Valley-polarized quantum anomalous Hall phase and disorder induced valley-filtered chiral edge channels
Hui Pan, Xin Li, Hua Jiang +2
We investigate the topological and transport properties of the recently discovered valley-polarized quantum anomalous Hall (VQAH) phase. In single layer, the phase is realized thro…
Valley-polarized quantum anomalous Hall phases and tunable topological phase transitions in half-hydrogenated Bi honeycomb monolayers
Cheng-Cheng Liu, Jin-Jian Zhou, Yugui Yao
Based on first-principles calculations, we find novel valley-polarized quantum anomalous Hall (VP-QAH) phases with a large gap-0.19 eV at an appropriate buckled angle and tunable t…
Intervalley coupling by quantum dot confinement potentials in monolayer transition metal dichalcogenides
Gui-Bin Liu, Hongliang Pang, Yugui Yao +1
Monolayer transition metal dichalcogenides (TMDs) offer new opportunities for realizing quantum dots (QDs) in the ultimate two-dimensional (2D) limit. Given the rich control possib…
Topological edge states in single- and multi-layer BiBr
Jin-Jian Zhou, Wanxiang Feng, Gui-Bin Liu +1
Topological edge states at the boundary of quantum spin Hall (QSH) insulators hold great promise for dissipationless electron transport. The device application of topological edge…
Time-reversal-invariant topological superconductivity in n-doped BiH
Fan Yang, Cheng-Cheng Liu, Yu-Zhong Zhang +2
Intrinsic and symmetry protected topological states have attracted lots of interest in condensed matter physics recently. In particular, time reversal symmetry protected fermion to…
Large-Gap Quantum Spin Hall Insulator in single layer bismuth monobromide BiBr
Jin-Jian Zhou, Wanxiang Feng, Cheng-Cheng Liu +2
Quantum spin Hall (QSH) insulators have gapless topological edge states inside the bulk band gap, which can serve as dissipationless spin current channels protected by the time-rev…
