摘要

We comparatively fabricated thin films of La0.01Ba0.99TiO3(LBTO)(,) Sm0.5Sr0.5CoO3(SCO) and Sm0.5Sr0.5CoO3/La0.01Ba0.99TiO3 (SCO/LBTO) thin films grown on quartz substrates using pulsed laser deposition technique. The structure of these samples was carried out using X-ray diffraction, and these samples had a polycrystalline structure. The surface topography for these films was studied using scanning electron microscopy (FE-SEM) and shows grains with nano-sized and uniform nature of the thin films. The optical properties such as transmittance, absorbance and reflectance of these thin films were studied. The optical results such as absorption coefficient, optical energy gap and refractive index were determined. The oscillation energy and dispersion energy, on the other hand the dielectric results such as dielectric loss and dielectric tangent loss, were determined, while nonlinear optical results such as the third-order nonlinear optical susceptibility chi((3)) were calculated for all these samples. Finally, the electronic results such as the density of state for both the valence and conduction band were determined.
