The features of the growth process, defect structure, and photoluminescence of ZnTe crystallites obtained on the crystallizer walls at 650C, under the conditions of rapid deposition, from supersaturated source-component vapours were studied. It was found that each separate crystallite, whose size could be as large as 10mm, has a common [011] axis around which several individuals were twinned. Perfect fragments of separate individuals were packed in a single system of plane (110) macrolayers, each reaching a thickness of several tens of micrometers. A 0.8mm-thick single-crystal platelet that has (110) growth layers on one side was crossed by a system of (1¯11) twin boundaries perpendicular to the growth surface, with the number of boundaries decreasing at the outer growth surface. The photoluminescence spectra confirmed the structural perfection of the obtained crystals.
