Abstract
In this paper, we report a theoretical study of the diffusion of positrons to the surface for a semi-infinite medium and a film with a thickness of d in semiconductors by using a δ-function method. The results can be used to the analysis of experimental data for the overlayer/substrate system which contains one film or several films and a semi-infinite medium.
