Characterization of as-produced carbon nanotubes. (a and b) Representative SEM images of CVD-grown horizontally aligned CNT nucleated from pristine fullerenes (C60) and exohedrally functionalized fluorofullerenes (C60F18), respectively. (c, d, and e) TEM micrograph, RBM of the Raman spectroscopy, and AFM image of catalyst-free SWCNT, respectively. An inset is the height profile of the nanotube shown in panel e.
