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…
A hard metallic material: Osmium Diboride
Z. Y. Chen, H. J. Xiang, Jinlong Yang +2
We calculate the structural and electronic properties of OsB2 using density functional theory with or without taking into account spin-orbit (SO) interaction. Our results show that…
Efficient construction of 2-D cluster states with probabilistic quantum gates
Qing Chen, Jianhua Cheng, Ke-Lin Wang +1
We propose an efficient scheme for constructing arbitrary 2-D cluster states using probabilistic entangling quantum gates.In our scheme, the 2-D cluster state is constructed with s…
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…
Theoretical determination of the necessary conditions for the formation of ZnO nanorings and nanohelices
Z. C. Tu, Q. X. Li, X. Hu
The formation of ZnO nanorings and nanohelices with large polar surfaces observed in experiments [Nano Lett. 3, 1625 (2003); J. Am. Chem. Soc. 126, 6703 (2004)] is shown to be a re…
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…
