Abstract

Thin film heterostructures of BaTiO3/YBa2Cu3O7-x (YBCO) and BaTiO3/LaxSrl-xCoO3 (LSCO) have been prepared by a novel single liquid source plasma-enhanced metalorganic chemical vapor deposition (PE-MOCVD) process. Both YBCO and LSCO are conductive oxides with perovskite structure and lattice parameters closely matched to BaTiO3. YBCO films were found to deteriorate after the deposition of BaTiO3 under the PE-MOCVD conditions as revealed by X-ray diffraction and electrical characterization. LSCO thin films prepared by PE-MOCVD have a mirror-like surface, exhibit low electrical resistivity (p = 200 μΩ-cm at room temperature) and are robust to BaTiO3 deposition. These characteristics make LSCO a promising electrode material for ferroelectric capacitors.
