Polytypic Structures in MX Compounds: ZnS and Znsub(1-X)Cdsub(X)S

摘要

Polytypic structures in ZnS and Znsub(1-x)Cdsub(x)S single crystals have been investigated. The basic hexagonal 2H and cubic 3C structures, polytypes and nonperiodic structures were observed both in pure and mixed crystals. It was found that the average percentage of layers in hexagonal arrangement in the crystals increases with increasing growth temperature as well as with Cd-content in the crystals. The results of the investigations, with respect to various theories of polytype formation, are discussed. (Atomindex citation 15:007532)
