  • Abstract
    Results of a systematic study of damage generation and accumulation until amorphization induced by 180 keV Ca+ implantation in GaN films at liquid-nitrogen and room temperature are compared. The as implanted films show an expanded lattice. An initial amorphous component was found after implantation with a dose of 3×1014 and 8×1014 cm-2 at liquid-nitrogen and room temperature, respectively. The mechanism of amorphization is discussed and accumulation of amorphous clusters seems to be the reason for the collapse of the GaN crystalline state
