a, b Copper foil, used as a substrate after the CVD, looks very similar to that of the original copper foil. c GrPyC transferred on a silica substrate and on Si/SiO2 (300 nm)—inset. d, e A closer look with an optical microscope and scanning electron microscope shows that although there are wrinkles all around the sample, there are no color nor contrast differences which indicate very uniform film thickness
