## Abstract In this paper, we discussed a general multidimensional nonisentropic hydrodynamical model for semiconductors with small momentum relaxation time. The model is selfβconsistent in the sense that the electric field, which forms a forcing term in the momentum equation, is determined by the
A mechanism for diffusion in solid metals is proposed in which the rate-limiting atom movements occur within small regions of disorder in the crystal. The disordered regions consist, on the average, of 12 to 14 atoms which have relaxed inward around a lattice vacancy, and have an energy content abou
