1. Electric properties of organic molecules measured by nano-gap electrodes: I have fabricated nano-gap electrodes with 10〜100 nm gaps in order to clarify the conduction mechanisms of single or small number of molecules. A ruthenium complex molecule was trapped between the electrodes and was measured the electric properties at various temperature to show that there are several mechanisms depending on the temperature.2. Development of a new method for fabricating nano-gap electrodes utilizing self assembling of molecules and electron beam lithography: By using self-assembling of molecules and electron beam lithography, nano-gap electrodes with 5 20 nm could be fabricated, which was used for making single electron devices.3. Preparation of giant molecules and their self organization on solid surfaces : Porphyrin oligomers and polymers were prepared, and their topographic structures on solid surfaces were controlled.4. Preparation of gold nano-particle / organic molecule assemblies between micro gap electrodes, and studies on their electric properties: Gold nano-particle / organic molecule assemblies were prepared between micro gap electrodes, and their electric properties were studied at various temperature to show a electric conduction through the molecular orbital.5. Self organization of carbon nanotube / organic molecule assemblies and studies on their electric properties : Electric properties of organic molecules were studied using carbon nanotubes as the electrodes and PCI-AFM. We found that on semi-conductive carbon nanotubes the molecules showed rectifying property and on metallic carbon nanotubes they showed semi-conductive properties.

1.通过纳米间隙电极测量有机分子的电特性：为了阐明单个或少量分子之间捕获的钌络合物分子的导电机制，我制作了间隙为10-100 nm的纳米间隙电极。电极并测量了不同温度下的电性能，表明存在多种取决于温度的机制。 2．开发了一种利用分子自组装和电子束制造纳米间隙电极的新方法。光刻技术：利用分子自组装和电子束光刻技术，可以制备出5~20 nm的纳米间隙电极，用于制作单电子器件。3．巨型分子的制备及其在固体表面的自组织：卟啉。制备低聚物和聚合物，并控制其在固体表面的形貌结构。4．微间隙电极间金纳米颗粒/有机分子组装体的制备及其电学研究。性质：在微间隙电极之间制备金纳米颗粒/有机分子组装体，并在不同温度下研究其电学性质，以显示通过分子轨道的导电性。 5．电学性质：以碳纳米管为电极，通过PCI-AFM研究了有机分子的电学性质，我们发现，在半导体碳纳米管上，分子表现出整流性，而在金属性碳纳米管上，则表现出整流性。显示出半导体特性。
