Outline of Final Research Achievements |
In order to understand the detailed mechanism of surface reactions, it is desirable to directly observe the local structure of adsorbed molecules on material surfaces. However, the conventional spectroscopy has the limitation on spatial resolution nearly wavelength of light owing to the diffraction limit. In this research, we tried to develop a new microspectroscopy system with high spatial resolution and high sensitivity by using near-field effect with setting adsorbed hydrogen atoms on metal surfaces as a model system. We succeeded in developing the optical setup and detecting the signal just under the metal tip.

Academic Significance and Societal Importance of the Research Achievements |
本研究で行った測定手法の開発は、吸着分子のミクロな局所構造を観測し、それがマクロな反応性とどのように関わっているのかを理解するための基礎的な観測手段を与えるものとなりうる。表面反応メカニズムの詳細を理解できるようになれば、物質表面のミクロな構造を制御することで、反応の選択制や活性を高める新しいタイプの触媒の設計指針を与えることにもつながると期待される。
