Valley-polarized quantum anomalous Hall effect in van der Waals heterostructures based on monolayer jacutingaite family materials
Xudong Zhu, Yuqian Chen, Zheng Liu +2
We numerically study the general valley polarization and anomalous Hall effect in van der Waals (vdW) heterostructures based on monolayer jacutingaite family materials PtAX$_…
Large-Gap Quantum Anomalous Hall Effect in Monolayer Halide Perovskite
Zeyu Li, Yulei Han, Zhenhua Qiao
We theoretically propose a family of structurally stable monolayer halide perovskite ABC (A=Rb, Cs; B=Pd, Pt; C=Cl, Br) with easy magnetization planes. These materials…
Interlayer Ferromagnetism and High-Temperature Quantum Anomalous Hall Effect in \textit{p}-Doped MnBiTe Multilayers
Yulei Han, Shiyang Sun, Shifei Qi +2
The interlayer antiferromagnetic coupling hinders the observation of quantum anomalous Hall effect in magnetic topological insulator MnBiTe. We demonstrate that interlayer…
Van der Waals Heterostructure PtHgSe/CrI for Topological Valleytronics
Zheng Liu, Yulei Han, Yafei Ren +2
We identify a valley-polarized Chern insulator in the van der Waals heterostructure, PtHgSe/CrI, for potential applications with interplay between electric, magneti…
Berry-Curvature Exchange Induced Anderson Localization in Large-Chern-Number Quantum Anomalous Hall Effect
Hui Yang, Junjie Zeng, Yulei Han +1
We theoretically investigate the localization mechanism of quantum anomalous Hall Effect (QAHE) with large Chern numbers in bilayer graphene and magnetic topological…
Mesoscopic Electronic Transport in Twisted Bilayer Graphene
Yulei Han, Yafei Ren, Xinlong Dong +3
We numerically investigate the electronic transport properties between two mesoscopic graphene disks with a twist by employing the density functional theory coupled with non-equili…
