摘要：

Highly textured BZY and BZCY films were fabricated on a single crystalline MgO(100) substrate by PLD under various deposition conditions including substrate temperature and target-to-substrate distance. The perovskite-type oxides, BaZr0.85Y0.15O3-delta (BZY) and BaZr0.3Ce0.55Y0.15O3-delta (BZCY), were synthesized via a solid-state reaction method and sintered at 1680 degrees C to be used as targets for pulsed laser deposition (PLD). The structural properties of the films were analyzed by x-ray diffraction (XRD) and scanning electron microscopy (SEM). The electrical conductivities of the films were measured by the electrochemical impedance spectroscopy (EIS) method in the temperature range of 220-460 degrees C.
