| Research Abstract |
I attempted to extend "SR-STM" that is a method of elemental-analysis having an atomic resolution. SR-STM is to analyze the elemental composition of samples by giving the inner-shell information derived from the excitation to STM that observes only the shallow electronic level. In this project, SR-STM, which has long served only to semiconductors, was applied to new systems (metal, metal-containing organic molecules (phthalocyanine: Pc)). Although there were difficulties such as measurement instability and radiation damages, after improvement of light source, the element-contrast on metals has been observed for the first time. Finally, SR-STM was applied to the analysis of metal-Pc. The clear modification of the contrast was not observed across the metal-absorption-edge of the incident X-ray energy, whereas a specific radiation effect was newly observed for a metal-Pc, which gives hope to enable the element-specific analysis and/or reaction control of molecules in future.
