Outline of Final Research Achievements

We fabricated Y2O3, CeO2, YSZ, CSZ, and YBa2Cu3O7 thin films on {110}<001> textured silicon steel plates, (110) Fe single crystals, and {110}<110> textured Ag tapes. The crystal orientations of the obtained thin films were measured, and the orientation relationships between the substrate crystals and the crystals in the thin films were determined. As the lattice mismatch between the substrate crystals and the deposited thin film crystals increased, a large number of crystal orientations tended to coexist. However, there were some exceptions, further investigation has to be conducted.

Academic Significance and Societal Importance of the Research Achievements

不整合ヘテロエピタキシャルのメカニズム解明には至らなかったが、多数のデータを収集することができ、珪素鋼板、Agといった金属基板上にいくつかの酸化物の疑似単結晶薄膜を成長させることに成功した。今後、さらに多くのデータを集めて解析することで不整合ヘテロエピタキシャル成長メカニズムの解明が進むと期待される。また、各種単結晶基板より安価であり熱伝導率が高い金属単結晶が基板材料として使用できることを示すことができたと考えるが、この成果を活用することで各種デバイスの放熱性を大きく向上させることが可能になるなど産業への活用も見込めると考える。
