Electron Impact, Heat, and Transport Phenomena in Solids.

Abstract

The theory of nonequilibrium transport processes is reviewed, generalized, and extended. The weakness of the heat equation is discussed, a generalized transport equation based on the Boltzmann equation is developed, and its validity in terms of the Liouville equation, the R-particle reduced distribution function, and the B-B-G-K-Y hierarchy is discussed in the framework of the Bogoliubov initial, kinetic, and hydrodynamic time regimes. Viscous hydrodynamic theory is reviewed and transport moment methods are generalized in phase space; the basic semiconductor equations with sources and sinks are derived from the transport moment equations. Drift and heat current densities are developed. Thermal and electrical conductivities are discussed. Nonequilibrium transport processes are discussed for solids subjected to electron bombardment for low dose irradiation and high energy-density pulsed beams. A formulation for electron beam bombardment in the diffusion approximation regime is developed. (Modified author abstract)
