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 gamma equals 85 plus or minus 21 mJ m** minus **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.
