Abstract

A Sol-gel derived ferroelectric PbTiO3 thin film was synthesized by using diethanolamine (DEA) as a comple-xing agent. Surface chemical analyses were examined in order to study the effect of heating temperature on the composition of thin film by EPMA and XPS. A rapid volatilization of lead was observed in the films fired at $700^{\circ}C$ or higher and the ratio of Pb:Ti was found to be 34:66. A depth profile by Ar+ showed that the Ar sputtering decreased Pb amount of inner part of the film resulting in Ti-rich phase near the surface of the film.
