摘要

结果表明，半导体异质结构中均相的自旋极化电子气体可以驱动电流。本文报道了这种自旋电偶效应，其中自旋极化是通过光学取向应用圆偏振远红外激光辐射实现的。这种效应的微观起源是自旋翻转散射固有的不对称性。

Infrared spin orientation and spin-galvanic effect in semiconductor heterostructures

It is shown that a homogeneous spin-polarized electron gas in semiconductor heterostructures can drive an electric current. Here we report on this spin-galvanic effect where the spin polarization has been achieved by optical orientation applying circularly polarized far-infrared laser radiation. The microscopic origin-of the effect is an inherent asymmetry of spin-flip scattering.
