Abstract

Multilayer epitaxial ferroelectric PbTiO3 and SrTiO3 thin films were grown alternatively on single crystal SrTiO3 (001) substrate by the sol-gel technique in this study. Lead titanium double metal alkoxide and strontium titanium double metal alkoxide were used for dip coating. By controlling the dip coating speed and the concentration of sol-gel solution, different thickness of films was obtained. The average thickness of each PbTiO3 or SrTiO3 layer was 120 Å which was measured by SEM method. By using XRD the structure of the epitaxial multilayer films was examined. The epitaxial PbTiO3 and SrTiO3 thin films could be obtained at 700°C and 800°C respectively. The change of transmittance with wavelength on 12( 6×[SrTiO3/PbTiO3]) layer films was measured. The structure and the optical properties of the films were discussed.
