非立方晶体中的内禀自旋霍尔效应

Intrinsic spin Hall effect in noncubic crystals

E. M. Chudnovsky

摘要:

我们研究了内禀自旋霍尔效应与晶体对称性和实验几何的关系。得到了自旋电流,并计算了电子自旋极化引起的霍尔电压。效应对晶体对称性的独特依赖性允许选择几何形状,其中自旋霍尔效应可以明确地与由于载流子的轨道运动和由于由传输电流产生的磁场的效应区分开。

英文摘要:

We study the dependence of the intrinsic spin Hall effect on the crystal symmetry and geometry of experiment. The spin current is obtained and the Hall voltage caused by the polarization of the electron spins is computed. The unique dependence of the effect on the crystal symmetry permits the choice of geometry in which the spin Hall effect can be unambiguously distinguished from the effects due to the orbital motion of charge carriers and due to the magnetic field generated by the transport current.
