Spin relaxation in n-doped gallium arsenide due to impurity and electron-electron Elliot-Yafet scattering

We calculate the spin relaxation time of conduction electrons in n-doped bulk gallium arsenide. We consider the Elliot-Yafet spin-relaxation mechanism, driven by Coulombic-impurity and electron-electron scattering. We find that these two scattering mechanisms result in relaxation times of equal order of magnitude, but with disimilar dependences on doping density and temperature. Our theoretical results are compared with experimentally measured spin relaxation times in gallium arsenide.
