| Outline of Final Research Achievements |
We investigated the electronic state of the surface and interface of molecular thin films in which semiconductor functions are expected by high-sensitivity ultraviolet photoelectron spectroscopy (UPS) and high-resolution angle-resolved UPS using synchrotron radiation. The correlation between the adsorption structure and the electronic state due to weak van der Waals interaction was precisely evaluated by making full use of various analytical methods, and the mechanism of function and materials properties was discussed from the viewpoint of electron localization. We also succeeded in evaluating the localization of conduction band structure for the first time for organic-inorganic hybrid perovskite crystal, which is expected as next-generation energy conversion materials.
