Abstract

Thin films of PbTiO₃ have been prepared on soda-lime glass substrates. The sol was prepared by mixing tetrapropyl orthotitanate and lead acetate trihydrate in acetic acid. The films were deposited by spin coating and annealed at 500 °C for 30 min. The structural and optical properties of the films were characterized by means of X-ray diffraction, atomic force microscopy, variable angle spectroscopic ellipsometry, UV-VIS spectroscopy, micro-Raman spectroscopy and the m-line technique. The electrical properties of the film were studied with a Sawyer-Tower bridge. The films have a pure perovskite phase with a c/a ratio of 1.054 and consist of crystallites with a size of a few tens of nanometers. Raman studies show the typical phonon modes of PbTiO₃, and the shift of the Raman peaks indicates that the films are stressed. The films are highly transparent and the absorption edge is approximately 3.70 eV. A two-layer film is found to support two TE and two TM modes at a wavelength of 633 nm.
