Outline of Final Research Achievements

Increasing attention is being paid to hydrogen-related science and the creation of innovative materials, devices, and reaction processes through higher-order hydrogen functionality. Controlling the behavior of hydrogen at interfaces will enable continuous changes in hydrogen density and the development of innovative devices and materials.
In Stage I, we succeeded in synthesizing metal hydride thin films and complex hydride thin films and established fundamental technologies for synthesizing complex hydride thin films. In Stage II, we pioneered new properties at hetero-interfaces, developed visualization technology for hydrogen concentration distribution, and improved solar cell performance through interface control. In Stage III, we advanced research on higher-order hydrogen functions using cutting-edge measurement techniques and computational analysis.

Academic Significance and Societal Importance of the Research Achievements

水素の多彩な機能に注目し、特に界面局在に着目して界面制御技術を創出したい。それにより、材料設計指針の構築と革新的デバイスの創製を通じて、新しい水素科学の構築に貢献する。本研究では、ヘテロ界面における水素の役割を明らかにし、異分野と連携しながら新材料の合成や物性制御を行った。さらに、先端計測・シミュレーションを活用して新しい水素科学の構築を行い、多彩な高次水素機能の開拓を進めた。
