Spin Bias Measurement Based on a Quantum Point Contact
Yanxia Xing, Qing-feng Sun, Jian Wang
Electron charge transport through a quantum point contact (QPC) driven by an asymmetric spin bias is studied. A large charge current is induced when the transmission coefficient of…
Spin Nernst effect and Nernst effect in two-dimensional electron systems
Shu-guang Cheng, Yanxia Xing, Qing-feng Sun +1
We study the Nernst effect and the spin Nernst effect, that a longitudinal thermal gradient induces a transverse voltage and a spin current. A mesoscopic four-terminal cross-bar de…
Double quantum dot as detector of spin bias
Qing-feng Sun, Yanxia Xing, Shun-Qing Shen
It was proposed that a double quantum dot can be used to be a detector of spin bias. Electron transport through a double quantum dot is investigated theoretically when a pure spin…
Influence of dephasing process on the quantum Hall effect and the spin Hall effect
Yanxia Xing, Qing-feng Sun, Jian Wang
We study the influence of the phase relaxation process on Hall resistance and spin Hall current of a mesoscopic two-dimensional (2D) four-terminal Hall cross-bar with or without Ra…
Nature of Spin Hall Effect in a finite Ballistic Two-Dimensional System with Rashba and Dresselhaus spin-orbit interaction
Yanxia Xing, Qing-feng Sun, Jian Wang
The spin Hall effect in a finite ballistic two-dimensional system with Rashba and Dresselhaus spin-orbit interaction is studied numerically. We find that the spin Hall conductance…
Opposite spin accumulations on the transverse edges by the confining potential
Yanxia Xing, Qing-feng Sun, Liang Tang +1
We show that the spin-orbit interaction induced by the boundary confining potential causes opposite spin accumulations on the transverse edges in a zonal two-dimensional electron g…
