Abstract

Dislocations of a/2<110> Burgers vectors lying in {001} and {111} planes in the form of cross-grids are often observed in ion implanted and thermally annealed specimens. In order to asses the mechanism of formation of these dislocations, we have calculated energies and determined atomic core structuresof a/2<110>{001} edge dislocations and their dipoles,and of a/2<110>{111} dislocations in silicon by minimizing the total configurational energy.
