Abstract
Dutt and Spitzer have experimentally observed the localized vibrational modes related to the phospherous defect in CdTe and reported that this defect may go either to substitutional or interstitial site. In this paper we study theoretically this phospherous defect behaviour for these two possible sites by Green's function technique and we believe that phospherous goes interstitially rather than substitutionally. The localized modes paired with Ga, In and Al are also investigated and discussed in the light of the experimental results.
