Abstract

Basal dislocations in CdS have been studied using the weak-beam method of electron microscopy. Networks of dissociated nodes and long lengths of dissociated dislocations were observed, from which the stacking fault energy was determined to be γ = 85 ± 21 mJ m−2. Dissociated dislocations were observed gliding while dissociated, both partials being visible during the motion. This motion was recorded on video tape, and shows conclusively that the dislocations glide while dissociated.
