Electronic properties in a quantum well structure of Weyl semimetal
Wen-Long You, Xue-Feng Wang, Andrzej M. Oleś +1
We investigate the confined states and transport of three-dimensional Weyl electrons around a one-dimensional external rectangular electrostatic potential. Confined states with fin…
Quantum entanglement of electrons in a biased 1D two-probe device
Yao-Sheng Li, Wen-Long You, Xue-Feng Wang
Electronic quantum entanglement between the central chain and the two electrodes in an infinite one-dimensional two-probe device system is studied. The entanglement entropy is calc…
Spin negative differential resistance in edge doped zigzag graphene nanoribbons
C. Jiang, X. F. Wang, M. X. Zhai
The nonlinear spin-dependent transport properties in zigzag graphene nanoribbons (ZGNRs) edge doped by an atom of group III and V elements are studied systematically using density…
Effects of Geometry and Symmetry on Electron Transport through Graphene-Carbon-Chain Junctions
Yao-Jun Dong, Xue-Feng Wang, Ming-Xing Zhai +4
The electron transport between two zigzag graphene nanoribbons (ZGNRs) connected by carbon atomic chains has been investigated by the nonequilibrium Green's function method combine…
Robustness of the helical edge states in topological insulators
Xue-Feng Wang, Yibin Hu, Hong Guo
Topological insulators (TI) are materials having an energy band gap in the bulk and conducting helical electronic states on the surface. The helical states are protected by time re…
Dynamic screening and plasmon spectrum in bilayer graphene
Wen-Long You, Xue-Feng Wang
We have theoretically studied the collective response properties of the two-dimensional chiral electron gas in bilayer graphene within the random phase approximation. The cooperati…
