非弾性電子トンネル分光（Inelastic Electron Tunneling Spectroscopy: IETS）を用いた単分子膜におけるトンネル電流の経路解明にむけて、IETSにおける探針先端の形状の影響を、走査トンネル顕微鏡と原子間力顕微鏡を組み合わせて調べた。探針先端の原子数が一個の場合、探針先端の原子数が三個の場合に比べて、Cu表面上のCO分子に対するIETSの強度が４倍程度大きくなることを見出した。この結果を、（a）全トンネル電流に対する分子を介したトンネル電流の割合、ならびに（b）分子を介したトンネル電流における非弾性トンネル過程の能率という二つの観点から解釈した。
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.
