| Outline of Final Research Achievements |
This study aimed to prepared Ca-Ti-O system compound films and to control their microstructures and crystal orientations by using a chemical vapor deposition technique operated under high-power laser irradiation, called laser CVD. The effects of deposition temperature on oriented textures of CaTiO3 films were investigated. We found that CaTiO3 films with strong orientations to (011) and (101) were grown at significantly high deposition rates, forming unique microstructures such as pyramidal and square facets. Can+1TinO3n+1 films with the Ruddlesden-Popper type crystal structure were deposited on Ti substrates. The Can+1TinO3n+1 films exhibited high formability of calcium phosphate precipitates by the immersion in simulated body fluid.
