Abstract

The extent of the cadmium-telluride-based solid solution along the CdTe-GaTe join at 737°C has been determined from the composition dependence of its unit-cell parameter. The cathodoluminescence spectra of CdTe-based solid solutions in the CdTe-GaTe and CdTe-Ga2Te3 systems have been measured. The 895-nm band observed in the 78-K spectrum of the Ga2Te3-containing solid solution is due to the [Ga ·Cd V Cd] radiative defect complex. The spectra of the CdTe-GaTe solid solutions seem to show a superposition of two lines close in position, attributable to the [Ga ·Cd V Cd] and [Ga ′Cd V Te] defect complexes.
