Electrical Properties of nano-scale conductors connected to fixed electrodes

深入了解纳米领域的导电是实现分子电子学，即将单个分子指定为电子部件的最终电路所必需的。在这项研究中，我们致力于纳米间隙电极的开发和分子电导率的精确测量，特别是在低温下。我们测定了表征分子桥的基本量——电子透射系数，发现氢和C_<60>形成了相当透明的分子桥。我们还澄清了石墨烯这种二维大分子的特殊导电特性。

Deep understanding of the electrical conduction in the nano-domain is necessary to realize the molecule electronics, ultimate electric circuits that designate individual molecules as electronic parts. In this research, we have engaged in development of nano-gap electrodes and precise measurement of molecular conduction especially at low temperatures. We have determined the electron transmission coefficients, fundamental quantity that characterizes the molecular bridge, and found hydrogen and C_<60> form rather transparent molecular bridges. We also clarified peculiar conduction properties of graphene, a two-dimensional macromolecule.
