Abstract

The fabrication of multilayered SrtiO₃/BaTiO₃ thin films on LaNiO₃-buffered Pt/Ti/SiO₂/Si substrates were investigated by sol-gel deposition method. The microstructure and cyrstalline phase of the grown films were investigated by X-ray diffraction, transmission electron microscopy and X-ray photoelectron spectroscopy. The dielectric properties, as a function of multiplayer periodicity were investigated. The results show that the dielectric constants increased first and then decreased as the individual layer thickness increased.
