摘要

The thermal conductivities and spin polarization induced by the temperature gradient are investigated in a Rashba spinorbit-coupled two-dimensional electron gas. In this spinorbit-coupled system in the presence of nonmagnetic or magnetic electronimpurity scattering, the WiedemannFranz law still holds. However, the spin polarization induced by the temperature gradient strongly depends on the property of impurities. The components of spin accumulation both perpendicular and parallel to the direction of the temperature gradient, and the thermally induced charge Hall conductivity may be nonzero for magnetic disorders.
