Optical and thermal characterization of barium titanate thin films prepared by metalorganic deposition

Abstract

Single phase barium titanate thin films prepared by metalorganic deposition and annealed at different temperatures were investigated by using various photothermal and optical methods. The data reported include refractive indices, optical losses, thermal diffusivities, as well as optical and thermal inhomogeneities. Structural analysis by using scanning electron microscopy and x-ray diffraction was carried out to correlate the thin film microstructures with the measured properties, both of which were found strongly dependent on the annealing temperature.
