【 摘 要 】

The formation of structural defects in grown from the vapour phase ZnS crystals after electron irradiation with energy of 400 keV and intensity of 1 - 4.1019e/cm2.s in situ in electron microscope was studied. It is shown that under electron irradiation the small dislocation loops in size of 2.5 - 45 nm and a density of 1.4-1011cm-2, as well as voids and fine particles of a new phase in size ≤10 nm are formed. These features can be identified from an analysis of moire fringe contrast as phase of ZnO2.
