Carrier Mobility Dependence of Electron Spin Relaxation in GaAs Quantum Wells

Abstract
We have investigated the electron mobility (µ) dependence and the electron quantized energy dependence of the electron spin relaxation time (τs) in n-type and undoped GaAs/AlGaAs multiple quantum wells at room temperature. τs ∝µ-1 obtained from the experimental results is consistent with the theoretical prediction based on the D'yakonov-Perel' theory.
