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…
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-dependent electron transport in a Rashba quantum wire with rough edges
Xianbo Xiao, Huili Li, Guanghui Zhou +1
We investigate theoretically the spin-dependent electron transport in a Rashba quantum wire with rough edges. The charge and spin conductances are calculated as function of the ele…
Local spin polarisation of electrons in Rashba semiconductor nanowires: effects of the bound state
X. B. Xiao, F. Li, Y. G. Chen +1
The local spin polarisation (LSP) of electrons in two typical semiconductor nanowires under the modulation of Rashba spin-orbit interaction (SOI) is investigated theoretically. The…
