In-situ observations b>' TEM reveal that dislocation velocity is not influencedby light illumination, indicating that the cause of the photoplastic effect (PPE) inII-Vl compounds is not a change in the dislocation mobility. Densities of disloca-tions and loops left after plastic deformation in light are about an order of magni-tude higher than those in darkness. These results together with the results ofmechanical tests and those given in Part I (J. Phys. Soc. Jpn. 49 (1980) 1909) leadto a conclusion that the PPE is caused by the decrease in mean free path of mul-tiplied dislocations. Jog formation by cross slip resulting in immobilization ofglide dislocations is considered to be enhanced by their interaction with chargedpoint defects that trap minority carriers generated by illumination.
