| Outline of Final Research Achievements |
Towards the investigation on the pass of tunneling electrons through the self-assembled monolayer by using inelastic electron tunneling spectroscopy (IETS), the role of a tip apex is investigated by combing scanning tunneling microscopy and atomic force microscopy. It was found that the tip whose apex consists of a single atom provides the four times larger IETS signal over the tip whose tip apex consists of three atoms. This finding was interpreted in terms of (1) the current ratio of a process through the molecule to that of the total current and (2) efficiency of the inelastic process for the process involving the molecule.
