摘要: Abstract Thin films of Ba1-xSrxTiO3 were prepared by off-axis laser deposition on MgO (001) and YBa2Cu3O7-δ coated SrTiO3 substrates. X-ray diffraction in Θ-2Θ geometry shows oriented film growth Ba1-xSrxTiO3. The epitaxial was proved pole figures reflection high-energy electron (RHEED) patterns. Atomic force microscopy (AFM) scanning (SEM) used to investigate the temperature dependence surface roughness grain size. Electrical properties measured a Sawyer-Tower circuit integration polarization current. For 800°C an oxygen pressure 0.4 mbar BaTiO3 show remanent about 5 μmC/cm2 at coercive field 55 kV/cm, dielectric constants 320 dissipation factors 0.02. e-T for different Ba-Sr stoichiometries. optical near bulk values.
