Volovichev I. Transport of nonequilibrium charge carriers in multicomponent plasma-like media

The thesis solves the actual problem of physical electronics - the study of transport of nonequilibrium charge carriers in plasma-like media and their interaction with electromagnetic fields. The object of the study is transport processes in plasma-like media with several types of non-equilibrium charge carriers, in particular, thermoelectric and photoelectric phenomena in bipolar semiconductors. The purpose of the thesis is to develop the linear diffusion-drift theory of transport processes in multicomponent systems for studying the interaction of nonequilibrium charge carriers with an electromagnetic field in solid-state plasma. The results are obtained using the method of successive approximations for nonlinear material equations of the classical electrodynamics’ problem, the finite difference method for solving differential equations. A general self-consistent system of boundary conditions for the stationary transport processes in semiconductor and metal structures in arbitrary combinations is obtained, a new model of recombination processes in non-uniform temperature fields for the linear diffusion-drift theory of transport processes in bounded plasma-like media with several types of charge carriers is proposed. The theory of thermoelectric phenomena for a medium with nonequilibrium charge carriers of several types is developed. A fundamentally new transverse dynamic thermoelectric effect is predicted. The results can be applied for measurements of semiconductor parameters, in the development of high-speed optoelectronic and other microelectronic devices, for increasing the efficiency of thermopower converters.
