The influence of CVD growth substrate morphology toward as-synthesized graphene electrical properties is explored through this work. It is demonstrated that ultrasmooth Cu growth substrates yield a substantial improvement in graphene transport properties, with a direct correlation between Cu surface roughness levels and subsequent graphene carrier mobility values being shown.
