Abstract

The application of the perturbed γγ angular correlation technique (PAC) as an analytical tool for the characterisation of atomic defect configurations is discussed, using recent results on donor-acceptor pairs, which were observed in CdTe and other II-VI semiconductors by the radioactive donor 111In. For bulk CdTe crystals and MOCVD grown CdTe films, the role of the cation vacancy, group I and group V elements is discussed.
