The purpose of this work are the following:1) The synthesis of the novel 2-dimensional conducting system on the basis of the interaction between metals and π electrons by using the self-assembly monolayer formed on the Au ultrathin films.2) The investigation of the chaotic conducting system and the possibility of a room temperature superconductivity.As results of this work are the following:1) We have developed the new process to prepare the C60 derivative (C60-O-C8SH) self-assembly monolayer (C60-SAM) on Au ultrathin films/MgO(100)single crystal.2) By AFM observation we demonstrated that nano-scale Au ultrathin films were prepared along to the steps formed of the clear step and terrace structures were fabricated by optimization of the annealing conditions. The obtained samples, C60-SAM/Au/MgO were the materials system corresponding to the room temperature superconductor model proposed by Little and Ginzburg.3) In some of the obtained samples the resistivity anomaly was observed at about 200K, when the micro-scale electrodes were fabricated for the resistivity measurements.These obtained results revealed the possibility of the room temperature superconductivity which will be clarified by the refinement of the sample preparation process and/or the detailed measurements of the sample characterization.

这项工作的目的如下：1）通过使用金属与π电子之间的相互作用，使用在AU超薄膜上形成的自组装单层来合成新颖的二维导电系统。2）混乱的导电系统的投资。 （C60-O-C8SH）AFM观察结果通过AU Ultrathin膜/MGO（100）单晶2）上的自组装单层（C60-SAM），我们证明，通过最佳化制造了纳米级Au Ultrathin膜，该纳米级AU超薄膜是通过确定的确定条件制造的。获得的样品C60-SAM/AU/MGO是与Little和Ginzburg提出的室温超导体模型相对应的材料系统。样品制备过程和/或样品表征的详细测量值。
