Spin-dependent hole quantum transport in Aharonov-Bohm ring structure: possible schemes for spin filter
J. Zhou, M. W. Wu, M. Q. Weng
We study the Aharonov-Bohm (AB) effect in two-dimensional mesoscopic frame in hole systems. We show that differing from the AB effect in electron systems, due to the presence of bo…
Spin relaxation under identical Dresselhaus and Rashba coupling strengths in GaAs quantum wells
J. L. Cheng, M. W. Wu
Spin relaxation under identical Dresselhaus and Rashba coupling strengths in GaAs quantum wells is studied in both the traditional collinear statistics, where the energy spectra do…
Schottky-barrier induced spin dephasing in spin injection
Y. Y. Wang, M. W. Wu
An ensemble Monte Carlo method is used to study the spin injection through a ferromagnet-semiconductor junction where a Schottky barrier is formed. It is shown that the Schottky-ba…
Spin-Hall effect in two-dimensional mesoscopic hole systems
M. W. Wu, J. Zhou
The spin Hall effect in two dimensional hole systems is studied by using the four-terminal Landauer-Büttiker formula with the help of Green functions. The spin Hall effect exists e…
Diffusion and transport of spin pulses in an -type semiconductor quantum well
L. Jiang, M. Q. Weng, M. W. Wu +1
We perform a theoretical investigation on the time evolution of spin pulses in an -type GaAs (001) quantum well with and without external electric field at high temperatures by…
