Abstract
In situ observations by TEM of deformation of CdS with the wurtzite structure and CdTe with the zinc-blende structure have shown that stacking fault ribbons are frequently formed by the motion of partial dislocations on the (0001) plane in CdS and on the {111} plane in CdTe. The motion of partial dislocations in both crystals was found to be steady and continuous, as also was that of perfect dislocations. These results suggest that dislocations in these crystals on the above planes are generally extended and that their motion is controlled by the Peierls mechanism.Keywords
