Heat generation by electric current in mesoscopic devices
Qing-feng Sun, X. C. Xie
We study the heat generation in a nano-device with an electric current passing through the device. For the first time, a general formula for the heat generation is derived by using…
Universal spin-Hall conductance fluctuations in two dimensions
Wei Ren, Zhenhua Qiao, Jian Wang +2
We report a theoretical investigation on spin-Hall conductance fluctuation of disordered four terminal devices in the presence of Rashba or/and Dresselhaus spin-orbital interaction…
Persistent spin current in a spin-orbit coupling/normal hybrid ring
Qing-feng Sun, X. C. Xie, Jian Wang
We investigate the equilibrium property of a mesoscopic ring with spin orbit (SO) interaction. It is well known that for a normal mesoscopic ring threaded by a magnetic flux, the e…
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…
Numerical simulations of a ballistic spin interferometer with the Rashba spin-orbital interaction
Zhenyue Zhu, Qing-feng Sun, Bin Chen +1
We numerically investigate the transport behavior of a quasi one-dimension (1D) square loop device containing the Rashba spin-orbital interaction in the presence of a magnetic flux…
