Outline of Final Research Achievements

For the chemical reactions on the surfaces, including catalytic reactions, some special sites of the surface like as the lattice defects play a critical role in the determination of the reaction path. However, the ratio of the number of defects against the total number of the surface atoms is tiny, which makes the chemical analysis difficult. STM can give local structure and electronic information. However, compare to the topography and the LDOS information, the spin information provided by ESR and NMR can give us higher sensitivity. In this research, we developed the techniques to identify the spin state of the molecules adsorbed on the surface.

Academic Significance and Societal Importance of the Research Achievements

スピンを化学分析に用いる手法は実は身近なところで大変重要になっており、医療で用いられるMRI検査も、核スピンを位置でマッピングしたもので、特定箇所の変化した化学状態を検知することで、たとえば癌の診断に用いられる。しかしその空間分解能はいまだミクロンスケールには達しておらず、本研究で行ったトンネル顕微鏡を用いた解析は本質的に原子レベルの分解法を持つが、現在熾烈な競争で開発が進んでいる。ナノスケールでの空間分解能をもったスピン検出が開発されたならば大きなインパクトを持つ。
