Abstract

AbstractThe problem of chemical shift of shallow donor states in compound semiconductors is investigated in the framework of pseudopotential theory. The “first principle” pseudo‐Hamiltonian including the electron–phonon interaction for shallow donor is obtained and the one‐band pseudo effective mass approximation is discussed. As an example the ionization energies for several donors in CdS and ZnSe are calculated. A good correspondence between the theory and experimental data for impurities in cation site is found.
