Abstract
First principles local-density-functional (LDF) theory is employed to inves tigate the properties of di-interstitial (I-2), tri-interstitial (I-3) and tetra-interstitial (I-4) structures in silicon. We show that a tri-intersti tial defect can account for many of the fundamental properties of the I-1/W -optical centre which is observed in irradiated, annealed silicon.
