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.

利用超薄一维碳纳米管空间合成了原子纳米线。采用激光蒸发和化学气相沉积法合成高质量、高纯度的碳纳米管是实现纳米管空间内原子线形成的关键之一。合成的原子线最细的直径只有一个原子厚，这是世界上最细的合成线。对于直径为两个原子厚的原子线，在室温下的TEM观察中，我发现了从锯齿结构到螺旋结构的可逆结构转变。除了合成新型纳米碳材料外，我还开发了使用微间隙电极的表征技术，该电极具有穿透衬底的通道，以详细阐明原子线的结构和性能之间的相关性。使用这种方法，原子结构表征，电子显微镜和器件特性测量上个别和特定的纳米管已成功地进行。
