摘要

Abstract

BSTRACTIon irradiation of KTaO

has been performed to investigate the evolution of irradiation damage with and without significant electronic energy deposition. Damage accumulation under irradiation with 2 MeV Au ions follows a direct-impact/defect-stimulated model

and occurs more rapidly than in SrTiO

under similar conditions. Electronic energy deposition from 21 MeV Ni ions creates negligible damage in pristine KTaO

to depths of 1 micron; however

damage is greatly enhanced in samples containing pre-existing defects

as evidenced by rapid amorphization due to track formation. The cross-sections for amorphous tracks show a nearly linear dependence on initial disorder

comparable with SrTiO
