| Research Abstract |
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.
