Abstract

We have employed photoluminescence measurements at 10-300°K to study the effects of deposition parame-ters, surfaces preparation and heat treatment on the properties of CdTe polycristalline thin films. The films were grown using a modified hot wall close spaced vapor transport system. We found strong differences in the photoluminescence spectra of samples grown under different conditions. Heat treatments in the as-grown samples increase the average particle size and reduce the native defect density.
