【 摘 要 】

We have investigated the synthesis and characterization of LaNiO3 (LNO) layers deposited on YSZ (100) substrate by metal–organic deposition (MOD). Texture, morphology and electrical properties of the LaNiO3 films were characterized by X-ray diffraction (XRD), atomic force microscopy (AFM), scanning electron microscopy (SEM) and electrical resistivity measurement. It has been found that the formation of (ℎ00) orientation depends on pyrolysis temperature, annealing temperature and thickness of LaNiO3 layers. The LaNiO3 films prepared under optimal condition indicate highly (ℎ00) orientation and a rather smooth surface. The LaNiO3 films show a metallic behaviour in the measured temperature range.
