Ion beam-induced epitaxial crystallization of the outer part of a buried amorphous layer was investigated after generating defects in the near-surface crystalline region by using 2.5keV Ar+ bombardment. It was shown that mobile defects which were produced more than 10nm from the amorphous/crystalline interface stimulated crystallization.
