✦ Synopsis
The model is an attempt to give an explanation of polytype orderings in the crystals. Basic assumptions of the model are: the point defects play the important part In the polytype formation; these defects influence the configuration (hexagonal or cubic) of individual layers. The defects have a tendency to ordenng themselves into superlattices. It acts selectively on particular stacking of the layer sequences. The results of model operation are shown in examples of experimental data of polytypic materials; they are Sic and A"BV1 compounds.
