To solve this issue, we demonstrated a modified gas phase reaction to achieve the large scale growth of contamination free graphene film, i.e., superclean graphene, using a metal containing molecule, copper(ii) acetate, cu(oac) 2, as the carbon source. during high temperature cvd, the cu containing carbon source significantly increased the cu.

Pretreatment of the cu substrate. alfa cu foil (alfa aesar no. 13382, 25 µm, 99.8%) was used as the substrate for graphene growth. the cu foil was cut to 2 cm × 2 cm and ultrasonically cleaned. In a growth temperature range between 1,000 k and 1,030 k, large area, fold free, single crystal single layer graphene films were produced on single crystal cu–ni (111) alloy foils (20.0 at% ni.
