Atomic nanowires have been synthesized using ultra-thin 1-dimensional nanospace of carbon nanotubes. One of the key to achieve the formation of atomic wire inside nanotube nanospace is to use high quality and high purity carbon nanotubes synthesized by laser vaporization and chemical vapor deposition method. Synthesized atomic wires have a diameter of one atom thick at thinnest, which is the world thinnest wires among ever synthesized. In the case of atomic wires whose diameter is two-atom thick, I have found that the reversible structural transformation from zigzag structure and helical structure occurs during TEM observations at room temperature. In addition to synthesis of novel nanocarbon materials, I have developed characterization technique using micro-gap electrodes with channel penetrating though the substrate to elucidate correlation between structure and properties of atomic wires in detail. Using this method, atomic structure characterization using electron microscopy and device characteristics measurement on individual and specific nanotubes have been successfully carried out.

原子纳米线已经使用超薄碳纳米管的超薄纳米空间合成。纳米管纳米空间内原子线形成的关键之一是使用通过激光汽化和化学蒸气沉积法合成的高质量和高纯度碳纳米管。合成的原子电线的直径为一个原子厚，这是有史以来合成的世界最薄的电线。对于原子电线的直径为两种原子厚，我发现在室温下在TEM观测期间，在TEM观测过程中发生了可逆的结构转换。除了合成新型纳米碳材料外，我还使用微型电极具有透明的底物，详细介绍了原子电线的结构和性质之间的相关性。使用这种方法，已经成功地进行了使用电子显微镜和设备特征测量的原子结构表征。
