ABSTRACTMulti-walled carbon nanotubes synthesized by the carbon arc in hydrogen gas have very thin core channels. We have measured resonance Raman scattering of some samples synthesized in different conditions, and have observed radial breathing mode (RBM) peaks from 200 to 500 cm−1. Resonance effect of each peak is similar to that of single-walled nanotube. However, the peak frequencies are about 5 % higher than those of single-walled nanotubes, which is probably due to the inter-layer interaction. Further, the highest RBM peak splits in three peaks. The result on the resonance effect and the zone-folding band calculation suggest that the thinnest core nanotube is (4,3) that have four candidates of second outer nanotubes. This suggests that the different outer nanotube gives different degree of the interlayer interaction.

This article examines the optical properties of single-wall carbon nanotubes (SWNTs) and nanographene. It begins with an overview of the shape of graphene and nanotubes, along wit the use of Raman spectroscopy to study the structure and exciton physics of SWNTs. It then considers the basic definition of a carbon nanotube and graphene, focusing on the crystal structure of graphene and the electronic structure of SWNTs, before describing the experimental setup for confocal resonance Raman spectroscopy. It also discusses the process of resonance Raman scattering, double-resonance Raman scattering, and the Raman signals of a SWNT as well as the dispersion behavior of second-order Raman modes, the doping effect on the Kohn anomaly of phonons, and the elastic scattering of electrons and photons. The article concludes with an analysis of excitons in SWNTs and outlines future directions for research.
