Coupled spin and valley physics in monolayers of MoS2 and other group-VI dichalcogenides
Di Xiao, Gui-Bin Liu, Wanxiang Feng +2
We show that inversion symmetry breaking together with spin-orbit coupling leads to coupled spin and valley physics in monolayers of MoS2 and other group-VI dichalcogenides, making…
Magnetic and Electronic Properties of Metal-Atom Adsorbed Graphene
Jun Ding, Zhenhua Qiao, Wanxiang Feng +2
We systematically investigate the magnetic and electronic properties of graphene adsorbed with diluted 3d-transition and noble metal atoms using first principles calculation method…
First-principles calculation of topological invariants Z2 within the FP-LAPW formalism
Wanxiang Feng, Jun Wen, Jinjian Zhou +2
In this paper, we report the implementation of first-principles calculations of topological invariants Z2 within the full-potential linearized augmented plane-wave (FP-LAPW) formal…
Quantum Spin Hall Effect in Silicene
Cheng-Cheng Liu, Wanxiang Feng, Yugui Yao
Recent years have witnessed great interest in the quantum spin Hall effect (QSHE) which is a new quantum state of matter with nontrivial topological property due to the scientific…
Topological Aspect and Quantum Magnetoresistance of -AgTe
Wei Zhang, Rui Yu, Wanxiang Feng +4
To explain the unusual non-saturating linear magnetoresistance observed in silver chalcogenides, the quantum scenario has been proposed based on the assumption of gapless linear en…
