DEFECT EQUILIBRATION STUDIES IN BINARY METAL-OXIDES

Abstract

The functional properties of metal-oxides are closely dependent on types and concentration ofdefects present in their lattice. Oxygen defects such as vacancies and interstitials are of particularinterest due to their role in affecting structural and physical properties. Vacancies in the oxygensub-lattice can increase leakage currents in dielectrics, enhance dielectric polarization, enablelocalized conducting filaments and in non-dilute concentrations lead to structural ordering andphase transitions. Oxygen interstitials can lead to lattice strain, hole conduction, and temperaturedependent anomalous conduction behavior when weakly bound or mobile.
