Unveiling the Direct Correlation between the CVD-Grown Graphene and the Growth Template

Figure 3

Optical (a–d) and SEM (e–h) images of graphene synthesized from various types of copper substrates and transferred onto the SiO₂ substrates and (i) the corresponding distribution on the ratio of monolayer to bilayer graphene formation. Red, blue, and white arrows indicate few layer graphene, wrinkles, and PMMA residues on the graphene, respectively.
