Plastic Deformation Behavior and Dislocation Structure of CdTe Single Crystals

Single‐crystal CdTe specimens were deformed in compression at 25°, 200°, 300°, and 500°C to various levels of plastic strain and to failure. Deformation characteristics at each temperature are given as curves of shear stress vs shear strain and the effect of test temperature on deformation behavior is examined. The dislocation structure of the CdTe samples deformed at high temperatures is examined using transmission electron microscopy. The relation between the deformation properties and the corresponding microstructure in CdTe is explored using previously developed models to describe metallic and nonmetallic crystalline materials.
