The effects of electron-electron interactions on the spin transport dynamics of a two-dimensional electron gas

arXiv:cond-mat/0012318

Abstract

Spin transport properties of a spin-polarized two-dimensional electron gas are studied in the presence of electron-electron interactions. Longitudinal and transverse spin diffusion coefficients are calculated with the quantum transport equation which includes many-particle effects in the random phase approximation. We find that the - scattering, which does not contribute to charge drift mobility, has a significant contribution to the spin diffusion. Thus, - interaction causes non-negligible effects on the operations of proposed devices dependent on spin transport in semiconductor heterostructures.
