Analysis of intensity. (a) Suspended and (b) supported graphenes. The plots of I(2D+), I(2D), and I(2D0) as functions of Φ. The symbol ‘I’ denotes the intensity of the corresponding sub-peak obtained by fitting the related Raman spectrum with a triple-Lorentzian function. The obtained intensities are shown by the dots, which are fitted by the form of Acos2(ΦΦ0) for I(2D+) and I(2D), and of a constant of A, where A and Φ0 are fitting parameters. The black and red lines display the fitting results.
