体相GaAs中的自旋轨道耦合

Spin-orbit coupling in bulk GaAs

J. Y. Fu, M. Q. Weng, M. W. Wu

摘要:

本文用$sp^3s^{\ast}d^5$和$sp^3s^{\ast}$最近邻紧束缚模型研究了GaAs布里渊区的自旋轨道耦合。在$Γ$ -谷中,得到的自旋分裂与实验数据符合得很好.然后,我们进一步明确提出的系数的自旋分裂GaAs $L$和$X$谷。这些结果对自旋电子器件的实现和远离平衡态自旋动力学的研究具有重要意义。

英文摘要:

We study the spin-orbit coupling in the whole Brillouin zone for GaAs using both the $sp^3s^{\ast}d^5$ and $sp^3s^{\ast}$ nearest-neighbor tight-binding models. In the $Γ$-valley, the spin splitting obtained is in good agreement with experimental data. We then further explicitly present the coefficients of the spin splitting in GaAs $L$ and $X$ valleys. These results are important to the realization of spintronic device and the investigation of spin dynamics far away from equilibrium.
