抄録

Ca-Ti-O films were prepared by MOCVD using Ca(dpm)₂ and Ti(OiPr)₂(dpm)₂ precursors. The phases, composition and morphology of Ca-Ti-O films changed depending on the molar ratio of Ca to Ti precursors (R_Ca/Ti), total pressure (P_tot) and substrate temperature (T_sub). CaTiO₃ films in a single phase were obtained at T_sub = 973 and 1073 K. CaTiO₃ films prepared at 873 K had a dense structure and smooth surface. CaTiO₃ films prepared at T_sub = 1073 K had complicated rough surface with a cauliflower-like texture. Hydroxyapatite (HAp) formed in 3 days on the CaTiO₃ film prepared at T_sub = 1073 K.
