The quality of the employed substrates plays a crucial role, since the surface roughness and defects alter the graphene growth and cause dif fi culties in the subsequent graphene transfer. Here, we report on ultrasmooth high- purity copper foils prepared by sputter deposition of Cu thin fi lm on a SiO 2 /Si template, and the subsequent peeling off of the metallic layer from the template. The surface displays a low level of oxidation and contamination, and the roughness of the foil surface is generally de fi ned by the template, and was below 0.6 nm even on a large scale. The roughness and grain size increase occurred during both the annealing of the foils, and catalytic growth of graphene from methane ( +- 1000 °C), but on the large scale still remained far below the roughness typical for commercial foils. The micro-Raman spectroscopy and transport measurements proved the high quality of graphene grown on such foils, and the room temperature mobility of the graphene grown on the template stripped foil was three times higher compared to that of one grown on the commercial copper foil. The presented high-quality copper foils are expected to provide large-area substrates suitable for electronic applications. ER -
