Abstract

In CdS crystals, the influence of ultrasound (US) pulses on photocurrent, thermally stimulated current and edge emission spectra was observed. The effect was found to intensify with dislocation density. The analysis of obtained results showed that US treatment resulted in the decrease of shallow donor density in crystal bulk and its increase in near dislocation regions. This process of donor gettering by dislocations was shown to be one of the mechanisms of electron-beam-pumped CdS-based lasers degradation.
