| Outline of Final Research Achievements |
With regard to functional core surface atomic-level analysis, we established sample preparation methods for SnO2 and CeO2, which enabled atomic-level analysis. The oxygen defects and (1x2) surface structure of rutile TiO2(110) surface were analyzed in detail, and it was clarified that the line defects are negatively charged and do not adsorb water. The structure of oxygen-depleted line defects was confirmed experimentally and computationally; the fabrication method of SnO2 surface was established and successfully observed with atomic resolution; the photocatalytic reaction on TiO2 surface was observed in real time and the lipid bilayer degradation rate of gold-loaded TiO2 was demonstrated; automated SPM technique was developed and monoatomic level measurement for a long time was possible. Automated SPM technology has been developed, enabling long-time measurements at the monoatomic level.
