Two-dimensional half Chern-Weyl semimetal with multiple screw axes
Wei Xu, Jiawei Yi, Hao Huan +3
Half topological states of matter and two-dimensional (2D) magnetism have gained much attention recently. In this paper, we propose a special topological semimetal phase called a 2…
Novel Chern insulators with half-metallic edge states
Yang Xue, Bao Zhao, Yan Zhu +5
The central target of spintronics research is to achieve flexible control of highly efficient and spin-polarized electronic currents. Based on first-principles calculations and k-p…
Origin of topologically trivial states and topological phase transitions in low-buckled plumbene
Yue Li, Jiayong Zhang, Bao Zhao +2
Combining tight-binding (TB) models with first-principles calculations, we investigate electronic and topological properties of plumbene. Different from the other two-dimensional (…
Strong magnetization and Chern insulators in compressed graphene/CrI van der Waals heterostructures
Jiayong Zhang, Bao Zhao, Tong Zhou +3
Graphene-based heterostructures are a promising material system for designing the topologically nontrivial Chern insulating devices. Recently, a two-dimensional (2D) monolayer ferr…
Coupling effect of topological states and Chern insulators in two-dimensional triangular lattices
Jiayong Zhang, Bao Zhao, Yang Xue +2
We investigate topological states of two-dimensional (2D) triangular lattices with multi-orbitals. Tight-binding model calculations of a 2D triangular lattice based on $\emph{p}_{x…
Chern insulators without band inversion in MoS2 monolayers with 3d adatoms
Xinyuan Wei, Bao Zhao, Jiayong Zhang +3
Electronic and topological properties of MoS2 monolayers endowed with 3d transition metal (TM) adatoms (V-Fe) are explored by using ab initio methods and k.p models. Without the co…
Quantum Spin-quantum Anomalous Hall Effect with Tunable Edge States in Sb Monolayer-based Heterostructures
Tong Zhou, Jiayong Zhang, Yang Xue +4
A novel topological insulator with tunable edge states, called quantum spin-quantum anomalous Hall (QSQAH) insulator, is predicted in a heterostructure of a hydrogenated Sb (SbH) m…
