CHANGES IN STRUCTURE OF ZNS CRYSTALS DUE TO MECHANICAL STRESSES

Using the direct X‐ray diffraction method which was worked out for the case of lattices built up of translationally equivalent layers for the determination of the rat of occurrences of structure elements in crystal regions consisting of 3, 4 and 5 layers, respectively, structure changes in ZnS crystals due to mechanical stresses were investigated. Forces acting parallel to the [110] direction induced a decrease in the number of stackings containing hexagonal elements and increase in the number of cubic stackings. A lattice region of a ZnS crystal having originally pure 4 H structure became heavily stacking faulted when polished parallel to the (110) plane; repeated polishing results in a twinned cubic structure.
