| Outline of Final Research Achievements |
3D atomic structures around dopants and defects in various compound and oxide semiconductors and their relation with functionalities have been elucidated by fabricating a large number of functional inorganic materials for holography measurements. Notable achievements are (1) the first observation of suboxidic structure around Co in room temperature ferromagnetic semiconductor Co-doped TiO2, and (2) the observation of microscopic structure in visible light photocatalyst Rh-doped SrTiO3 and clarification of relationship between the local structure and the photocatalytic activity. In addition, roles of various active sites were clarified by investigating 3D atomic structures and interfacial and surface structures in a large number of functional materials. Consequently, these results contributed to improvement of their functionalities and to development of new functional materials possessing new active sites.
