Abstract

Following helium implantation (50 keV, 5 × 1016 cm -2) at 800 °C in silicon, only {1 1 3} defects are present spreading out beyond the maximum of the damage distribution. Both linear rod-like defects as well as so-called ribbon-like {1 1 3} defects are observed. During annealing at 800 °C, the number of interstitials in ribbon-like defects appears to increase at the expense of the rod-like defects. After annealing at 1000 °C, only a row of dislocation loops is observed. These results suggest that the formation energy of the ribbon-like defects may be lower than that of the rod-like defects.
