| Research Abstract |
We have developed the measurement system for the vibrational spectroscopy of the single molecular junction. The electron transport properties and atomic configurations of the single benzene, ethylene, acetylene, fullerene molecules bridging between Au, Ag, Cu, Pt electrodes, have been investigated. The conductance of these single molecular junction was about 1Go, which was close to that of the metal atomic contact. We also investigated the electron transport through π-stacked systems using cage molecule.
