Dislocations in CdTe plastically deformed at room temperature
Journal Article

· Acta Metall.; (United States)
Two samples of cadmium telluride have been deformed in compression at room temperature. The applied stress was parallel to 110 in the matrix of the twinned crystal and to 131 in the twin. The other sample was deformed along an 132 direction. Activation of glide systems has been studied by transmission electron microscopy (TEM). The structure mainly contains segments of screw and 60/sup 0/ dislocations and edge dipoles resulting from dragging of jogs. All the dislocations are dissociated in two Shockley partials; the stacking fault energy ranges from 8.8 to 14.7 mJ x m/sup -2/.
