The pseudospin model for the G 1−x P x semiconductor alloy is considered in the coherent potential approximation. The phonon density of states in ultraheavily doped semiconductor thin films is investigated as a function of impurity concentration and the position of a monatomic layer inside the film. The obtained results show the dependence of the local density of states on the surface conditions.
