The problems on the main issues of semiconductor physics (statistics of electrons and holes in semiconductors, diffusion and drift of charge carriers, photo- and thermoelectric phenomena, etc.) are given. d. ). The second edition adds a number of new tasks (in particular, relating to semiconductors with a complex law of dispersion); a new chapter on semiconductor optics is also introduced. At the beginning of each chapter, a summary of the basic formulas is given, the tasks are provided with detailed solutions A-e ed. in 1968 . ); For students and postgraduates of universities and other universities training specialists in semiconductor physics, semiconductor materials science and semiconductor electronics .
