Abstract

The first section of this chapter describes layer stacking in close-packed structures. The structures of SiC and ZnS, CdI2 and GaSe are used as examples. Stacking faults, voids in structures and disorder are discussed. Layer stacking in general polytypic structures is described in the second section of the chapter. The notion of polytypism is explained and symmetry aspects of polytypism are considered. Three examples illustrating the three main methods of analysis of polytypism are given.
