Dislocations in Two Types of CdS Crystals

Abstract

Dislocation densities in CdS crystals (types I and II) have been investigated employing chemical etching techniques. There is very little difference in the dislocation densities in the two types of CdS crystals. The dislocation density in both types of growth varies over a range from 107/cm2 to 101/cm2. However, type I crystals have a greater tendency to twin and low angle boundaries are generally present in the twinned crystal.
