| Outline of Final Research Achievements |
Single-wall carbon naotubes (SWCNTs), which are typical nano-structural materials, were investigated by molecular dynamics calculations, X-ray diffraction (XRD) experiments, NMR experiments, and electric resistivity/Seebeck coefficient measurements. It was demonstrated that detailed structures of SWCNTs which include information on the bond length and chirality, can be obtained from powder XRD measurements even in non-crystalline samples. The effects of bundle metallicity on the one-dimensional electronic states of SWCNTs were clarified by NMR T1 measurements in high purity nonmagnetic samples. High purity samples free of magnetic impurity made it possible to investigate intrinsic magnetic properties of SWCNTs and its diameter dependence. Haldane magnet of oxygen molecules was realized in thin SWCNTs for the first time. Water inside SWCNTs with diameters larger than ~1.5 nm was extensively investigated. A giant Seebeck coefficient was discovered in semiconducting SWCNT films.
