HRTEM images, SAED patterns, and average Raman spectra from purified and annealed CNTs. (a, b) Representative HRTEM micrographs of tube walls of the samples CNTs_(AAO/650°C) and CNTs-2900 K, respectively. The inserts in (a) and (b) are the diffraction patterns taken in the respective micrograph. (c) The average Raman spectra obtained from several measurements on different locations on the samples.
