Abstract
A general model of various thermoactivated processes in the form of a “quasiparticle in a finite depth potential well” is proposed. The model is then used to perform quantum mechanical calculations which show that light-generated excitons or electron-hole pairs significantly change the rates of such processes as thermoactivation diffusion and defect generation, and evaporation and desorption of impurities. It follows from the evaluations carried out that radiationless recombination of electron excitations under conditions similar to those of laser annealing of semiconductors produces quite high values of such rates without heating the crystal to its fusion temperature.
