The focus is on the experimentally relevant case when the electron doping is such that the Fermi energy $\\epsilon_F$ and transport scattering time $\\tau$ satisfy $\\epsilon_F \\tau/\\hbar \\gg 1$, but sufficiently low that $\\epsilon_F$ lies below the bottom of the conduction band. Our theory is based on the spin density matrix and takes the quantum Liouville equation as its starting point. The scattering term is determined accurately to linear order in the impurity density.
