Role of electron-electron collisions for charge and heat transport at intermediate temperatures

In this paper, the authors study transport in the disordered electron gas at intermediate temperatures, where both elastic and inelastic scattering are important. It is shown that inelastic processes affect the electric conductivity only mildly, but strongly influence the thermal conductivity. For the Seebeck coefficient, the authors predict that inelastic scattering can generate a non-monotonic temperature-dependence and even a change of sign
