Abstract

Degeneracy of a photoelectron gas is shown to strongly affect spin polarized electron transport since the Pauli principle dictates a concentration dependence of the spin stiffness and of the mobility. This causes a spin dependence of the diffusion constant D. A spin-dependence of D as large as 50 % is measured using polarized microluminescence imaging in p⁺ GaAs thin films, revealing a novel spin filter effect. The charge diffusion constant also depends on spin via a second order effect.
