dc.description.abstractThe effects of oxygen annealing on the structural properties and leakage current behaviors of sol-gel-derived Bi3 25La0.75Ti 3O12-y ferroelectric thin films have been studied. The thin films were pyrolyzed in different atmospheric conditions including a fully oxygenized ambient of 1 bar and an evacuated ambient of less than 10 mbar. X-ray diffraction patterns of the deoxygenated films showed measurable shifts to a higher angle, indicating that each deoxygenated film had a smaller lattice constant than the oxygenated one. Scanning probe analysis showed well-developed grains and inhomogeneous and asymmetric bound charges in both samples. The leakage current behavior of the films was measured as a function of voltage and temperature and was explained on the basis of the Schottky-Simmons thermionic emission model. X-ray photoemission spectra showed that oxygen stability in Bi2O2 layers plays an important role in determining the level of leakage current in the films. © 2009 The Japan Society of Applied Physics.-
