| Outline of Final Research Achievements |
We investigated the charge transfer phenomena between defects on insulating surfaces and nanostructures by using AFM operating in various environments First, CO molecules on the Pd nanostructures on Al2O3(0001) surface was investigated. As a result, we succeeded in observing the adsorption of CO molecules near the periphery of the Pd nanostructure with atomic resolution. In addition, the contact potential difference of the entire nanostructure decreased with the adsorption, and the contact potential difference increased locally at the adsorption position of CO molecules. This result suggests that the electrons in the nanostructure were transferred to the CO molecules upon adsorption of CO molecules onto the Pd nanostructure. In addition, the charge state of the O2 molecule adsorbed on TiO2(110) surface was investigated, and the dissociated O atoms were successfully identified at the atomic level as having various charge states.
