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.用纳米间隙电极测量有机分子的电学性质：为了阐明单个或少量分子的导电机理，我制备了间隙为10~100 nm的纳米间隙电极。将一种Ru络合物分子捕获在电极之间，并测量了不同温度下的电学性质，表明存在几种依赖于温度的机理。开发了一种利用分子自组装和电子束光刻技术制备纳米间隙电极的新方法：利用分子自组装和电子束曝光技术，可以制备出尺寸为5~20 nm的纳米间隙电极，用于制作单电子器件。大分子的制备及其在固体表面的自组装：制备了卟啉齐聚物和聚合物，并控制了它们在固体表面的拓扑结构。微间隙电极间纳米金/有机分子组装体的制备及其电学性能研究：在微间隙电极间制备了纳米金/有机分子组装体，并对其在不同温度下的电性能进行了研究，表明其在分子轨道上具有导电性。碳纳米管/有机分子自组装及其电学性质的研究：以碳纳米管为电极，利用PCIAFM研究了有机分子的电学性质。我们发现，在半导体型碳纳米管上，分子表现出整流性质，而在金属碳纳米管上，它们表现出半导电性。
