Chemical Synthesis of Multilayered Nanostructured Perovskite Thin Films with Dielectric Features for Electric Capacitors

Journal Article


Abstract


  • We report a simple sol−gel method for the

    preparation of multilayered hybrid thin films composed of

    nanostructured SrTiO3 (STO) and BaTiO3 (BTO) layers. A

    nanoporous thin film of STO is prepared by the spin-coating

    method on Si/SiO2/Ti/Pt substrate. When the BTO is processed,

    the BTO is crystallized between STO crystal pores. A significant

    strain field is induced on the interface between the STO and BTO

    surfaces. The concave shape of the nanopores could enable the

    realization of a highly strained interfacial heterostructure composed

    of STO/BTO. Compared to nanostructured STO, BTO, and

    bilayer STO/BTO films, multilayered STO/BTO films show the highest dielectric constant and a high Curie temperature (Tc) at

    around 280 °C, which is suitable for electric capacitor applications.
