Abstract:Standard Monte Carlo methods for calculating diffusivity fail when the degeneracy of the electron gas is important. We apply a recently proposed Monte Carlo procedure in order to study diffusion coefficients in degenerate bulk GaAs at 77 K. Two sets of electrons are simulated, the first one representing the uniform 'background' electron density and the second one accounting for additional 'excess' electron concentration. The diffusion coefficients are calculated accounting for 'excess' electrons only. We compa… Show more
