Hot electron transport in semiconductors. (English) Zbl 0688.76064

Summary: A recent derived model for stationary flow of energy and charge carriers in semiconductors - consisting of a coupled system of nonlinear elliptic equations - is analyzed by the methods of singular perturbation theory. This analysis reveals the solution structure and justifies a modified version of the standard drift-diffusion approximation for charge carrier flow.
