Materials Research Society Symposia Proceedings 74: 357-364.0272-9172http://nrs.harvard.edu/urn-3:HUL.InstRepos:2843734Ion implantation damage and annealing results are presented for a number of crystalline oxides. In Al₂O₃, the amorphous phase produced by ion bombardment of the pure material first crystallizes in the (crystal-line) Y phase. This is followed by the transformaiton of Y-Al₂O₃ to a-Al₂O₃ at a well defined interface. The activation energy for of a alumina from y is 3.6 eV/atom. In CaTiO₃, the implantation-induced amorphous phase transforms to remain crystalline even after high implantation doses at liquid nitrogen temperatures. The near surface of KTaO₃ is transformed to a polycrystalline state after inplantation at room temperature or liquid nitrogen temperature.en-US
