Morphology of the grown SWCNTs: (a) representative TEM images of the SWNT materials. The inset is aHRTEM closeup showing nanotubes of 1.2 nm-diam. (b) Typical Raman spectrum of the nanotube materials, where the various RBM, D, and G bands are clearly identified. The inset shows a close-up of the RBM band located at 185 cm−1, corresponding to an individual SWCNT having a mean diameter of 1.2 nm in total agreement with the TEM analysis in (a).
