Abstract

We investigated the electronic properties of the radial single-walled carbon nanotubes (SWCNTs) by using the Raman and the UV-Vis-NIR spectroscopy. The radial SWCNTs for the analysis were synthesized by the arc-discharge method with Ce as a catalyst. The yield of the radial SWCNTs with 1.55 nm diameter and 60 nm length was as high as 20% in the soot. From the UV-Vis-NIR spectrum and the tangential mode of Raman spectra, the radial SWCNTs were confirmed to be composed of semiconducting (0.64 and 1.14 eV for Vs 1→Cs1 and Vs 2→Cs2) and metallic (1.60 eV for V m1→Cm1) nanotubes.
