Dislocation behaviour at room temperature in CdTe is studied in situ by boththe transnaission electron microscopy (TEM) and the scanning eIectr?on microscopywith the cathodolttminescence mode (SUM-CL). The etch-pitting xnethod is alsoused. It is found by the TEM observation that dislocations cross-slip frequently,though they are often widely dissociated and glide in pairs. The ?notion of dis-locations, including partials, is steady and continuous, indicating that the shortrange motion is controlled by the Peierls mechanisun. Semi-microscopic observa-tions by the SEM-CL and the etch-pitting method showed, however', that disloca-lions are apt to be immobilized and the defornaation proceeds by m.ultipIying newdislocations successively, suggesting that the mnacroscopic strain-rate is governedby the multiplication rate a?ad the mean free path which is cont?'olled possiblyby jog formation by cross slips.
