Figure 6From: Laser-induced etching of few-layer graphene synthesized by Rapid-Chemical Vapour Deposition on Cu thin filmsRaman Spectrum of CVD graphene at low power and long acquisition time. First Raman spectrum of not transferred CVD graphene grown on Cu, acquired with laser power 0.1 mW for 800 s. The pronounced baseline is typical of graphene Raman spectra acquired on Cu (Miao et al.2011).Back to article page
