Abstract
Electron backscattered diffraction (EBSD) is used to study the effect of huge-density structural vacancies (SVs) on the twins in defect zinc-blende (DZB) crystal Hg3In2Te6 (MIT) grown by the Bridgman method. Comparing with typical perfect zinc-blende (PZB) crystals, three types of twins with several differences are observed in MIT. EBSD and high-resolution transmission electron microscopy (HRTEM) analysis suggest that the twins are deformation twins. The differences between them are attributed to the suppression of high-density structural vacancy clusters on the glide of twinning dislocations. Besides, the residual strain of most twins is found to be higher than that of the corresponding matrices.
