Abstract

A Green's-function technique is used to study the vibrations of a substitutional impurity in CdS. Three cases have been investigated, corresponding to localized modes, gap modes, and in-band resonant modes. The theoretical results are in close agreement with experimental results for the gap mode of vibration of a Se impurity substituted for the S ion and the resonant mode of a Mn impurity substituted for the Cd ion in CdS.
