Abstract:
Positron Annihilation Lifetime Spectroscopy has been performed with a pulsed positron beam to investigate the nature and evolution of implantation-induced defects created in the track region (TR) of 800 keV (3)He ions at different fluences. At high fluence - 5x10(16) cm(-2) - lifetime decomposition exhibits a predominant (98
