Analysis of intensity. (a) Suspended and (b) supported graphenes. The plots of I(2D_{+}), I(2D_{−}), and I(2D_{0}) 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 Acos^{2}(Φ − Φ_{0}) for I(2D_{+}) and I(2D_{−}), and of a constant of A, where A and Φ_{0} are fitting parameters. The black and red lines display the fitting results.
