All-electric spin transistor based on a side-gate-modulated two-dimensional topological insulator
Xianbo Xiao, Ying Liu, Zhengfang Liu +3
We propose and investigate a spin transistor device consisting of two ferromagnetic leads connected by a two-dimensional topological insulator as the channel material. It exploits…
Anisotropic Quantum Confinement Effect and Electric Control of Surface States in Dirac Semimetal Nanostructures
Xianbo Xiao, Shengyuan A. Yang, Zhengfang Liu +2
The recent discovery of Dirac semimetals represents a new achievement in our fundamental understanding of topological states of matter. Due to their topological surface states, hig…
Rashba-Zeeman-effect-induced spin filtering energy windows in a quantum wire
Xianbo Xiao, Zhaoxia Chen, Wenjie Nie +2
We perform a numerical study on the spin-resolved transport in a quantum wire (QW) under the modulation of both Rashba spin-orbit coupling (SOC) and a perpendicular magnetic field…
Spin-filtering and charge- and spin-switching effects in a quantum wire with periodically attached stubs
Xianbo Xiao, Zhaoxia Chen, Zhiming Rao +2
Spin-dependent electron transport in a periodically stubbed quantum wire in the presence of Rashba spin-orbit interaction (SOI) is studied via the nonequilibrium Green's function m…
Spin-polarized current separator based on a fork-shaped Rashba nanostructure
Xianbo Xiao, Yuguang Chen
A scheme for a spin-polarized current separator is proposed by studying the spin-dependent electron transport of a fork-shaped nanostructure with Rashba spin-orbit coupling (SOC),…
Spin polarization direction switch based on an asymmetrical quantum wire
Zhonghui Xu, Xianbo Xiao, Yuguang Chen
A scheme for a spin polarization direction switch is investigated by studying the spin-dependent electron transport of an asymmetrical quantum wire (QW) with Rashba spin-orbit coup…
