Abstract

The microstructural evolution of Ne-ion-irradiated anatase TiO ₂/SrTiO₃ films was investigated. A defect denuded layer formed in the TiO₂ film near the TiO₂/SrTiO₃ interface after irradiation. The accumulation of defects at the TiO ₂/SrTiO₃ interface led to the formation of a continuous interfacial amorphous layer on SrTiO₃. Both observations are attributed to the interaction of defects with the interface. Present results reveal that a hetero-epitaxial interface between two different oxides can act as an effective sink to absorb irradiation-induced defects.
