Quantum anomalous Hall effect in atomic crystal layers from in-plane magnetization
Yafei Ren, Junjie Zeng, Xinzhou Deng +3
We theoretically report that, with \textit{in-plane} magnetization, the quantum anomalous Hall effect (QAHE) can be realized in two-dimensional atomic crystal layers with preserved…
Topological Phases in Two-Dimensional Materials: A Brief Review
Yafei Ren, Zhenhua Qiao, Qian Niu
Topological phases with insulating bulk and gapless surface or edge modes have attracted much attention because of their fundamental physics implications and potential applications…
Gate-controlled topological conducting channels in bilayer graphene
J. Li, K. Wang, K. J. McFaul +6
The existence of inequivalent valleys K and K' in the momentum space of two-dimensional hexagonal lattices provides a new electronic degree of freedom, the manipulation of which ca…
The positive piezoconductive effect in graphene
Kang Xu, Ke Wang, Wei Zhao +17
As the thinnest conductive and elastic material, graphene is expected to play a crucial role in post-Moore era. Besides applications on electronic devices, graphene has shown great…
Single-Valley Engineering in Graphene Superlattices
Yafei Ren, Xinzhou Deng, Changsheng Li +5
The two inequivalent valleys in graphene preclude the protection against inter-valley scattering offered by an odd-number of Dirac cones characteristic of Z2 topological insulator…
