On the the mathematical aspects of the theory of carrier transport in semiconductor devices. The subjects covered include hydrodynamical models for semiconductors based on the maximum entropy principle of extended thermodynamics, mathematical theory of drift-diffusion equations with applications, and the methods of asymptotic analysis. Это и многое другое вы найдете в книге Mathematical Problems in Semiconductor Physics. Lectures Given at the C.I.M.E. Summer School Held in Cetraro, Italy, June 15-22, 1998 (W. Allegretto, C. Ringhofer, Angelo Marcello Anile)
