Figure 8From: Laser-induced etching of few-layer graphene synthesized by Rapid-Chemical Vapour Deposition on Cu thin films2D peak evolution with number of Raman acquisitions. Behaviour of position and shape of 2D peak of Raman spectra acquired in the same spot of the sample: (a) graphene onto Cu substrate; (b) graphene transferred onto SiO2 substrate. (Insets: change in position and intensity of the single Lorentzian curves used to fit the 2D peak of the spectra).Back to article page
