In order to prevent the diffusion of sodium ions toward the indium tin oxide layer and BaTiO3 insulating layer, the deposition temperature should not be higher than 500-degrees-C. X-ray diffraction patterns showed that the BaTiO3 thin film deposited at 400-degrees-C was amorphous. The stoichiometry of the films was identified by Auger electron spectroscopy. Scanning electron microscopy results suggested that BaTiO3 thin films deposited at 400-degrees-C had smooth surfaces without defects such as pinholes and clusters, but surface flatness decreased at the deposition temperature of 550-degrees-C. The dielectric constant was 12.9. The breakdown voltage determined from current-voltage measurements was as large as 2 X 10(6) V/cm.
