Dislocation networks which were observed in CoSi2 islands that were grown epitaxially onto Si were compared with the results of dislocation dynamics calculations. The calculations exploited the fact that image forces played a relatively minor role as compared with line-tension forces and dislocation-dislocation interactions. Remarkable agreement was found, and it was concluded that this approach might be applied more generally to the study of dislocations in other mesostructures.
