Anisotropic transport in a two-dimensional electron gas in the presence of spin-orbit coupling

Schliemann, John ; Loss, Daniel



Abstract

In a two-dimensional electron gas as realized by a semiconductor quantum well, the presence of spin-orbit coupling of both the Rashba and Dresselhaus type leads to anisotropic dispersion relations and Fermi contours. We study the effect of this anisotropy on the electrical conductivity in the presence of fixed impurity scatterers. The conductivity also shows in general an anisotropy which can be ...
