Abstract : During the period of this report two areas of research activity have been emphasized. Attempts to prepare CdTe samples with band-edge fluorescent emission spectra correlated with the identity of impurity additions have been successful. A theoretical study of the shape of the absorption edge has been continued. In addition, research performed under this contract has stimulated a theoretical study which has accounted for a discrepancy between theory and experiment on the temperature dependence of the band gap in CdTe. The results on E sub g(T) are significant for a number of other compounds where the existence of a similar problem is well established.
