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.
