Abstract

We give an overview of experimental investigations and theoretical modeling of elastic interaction and transformations of dislocated micropipes in growing crystals. We consider elastic interaction of pair of micropipes, split of a micropipe into smaller dislocated micropipes and/or full-core screw dislocations, elastic interaction of micropipe steps, micropipe grouping and twisting. The models reviewed explain the experimental observations of ramified, twisted and grouped micropipes in silicon carbide.
