(a) Plot of GO coverage (black squares) and C-segment coverage (blue circles) on a Cu surface as a function of growth time at 240 °C based on the Raman structure. (b) Comparison of the Raman spectra of GO sheets that were grown on Cu at 240 °C for 5 min (blue), 15 min (green) and 120 min (black), and then transferred onto a SiO2 (300 nm)/Si substrate.
