Figure 8
AFM profiles of Gr (a) and CNT (b) samples. We observed a variation of around 80 nm for both samples. Raman spectrums of Gr (c) and CNT (d). Spectrum has characteristic G and 2D peaks of sp2 carbon systems along with defect peaks D,D′ and D + D′. The Raman spectrum of CNT also has RBM spectrums that can give us information about tube diameters.
