Paper Abstract

The local thermodynamic equilibrium as well as the non-equilibrium properties of crystal defects in semiconductors are discussed with emphasis on such configurations that allow for multiple ionization and electronic excitation. A system of rate equations is developed which describes the temporal change of the occupation numbers of the different energy levels; it includes the processes of free charge carrier capturing as well as thermal emission. The results of the investigation can be used, for example, to obtain a more realistic dynamic description of the occupation of the chromium induced energy levels in gallium arsenide which play an important role as recombination centers in material for fast photonic switching.
