Graphene synthesis by cvd on copper substrates.

As for the graphene synthesis by cvd it is beneficial to maximize the scale while maintaining the homogeneity of large area films as indicated by bae et al. One alternative method that has been researched involves the creation of cvd graphene on a copper cu substrate in this example cu is used as a catalyst in the reaction. Graphene is needed 1. Our research focused on synthesis of monolayer graphene on 25 µm thick copper cu substrates which allowed for lateral growth on the scale of many centimeters.

The graphene was grown using chemical vapor deposition cvd. However your target is to prepare the cu substrate for graphene synthesis so in this case small amount of oxygenated functional groups are beneficial. Since in our experimental conditions graphene was synthesized over the whole substrate surface including areas covered by copper fingers one may expect that the large area graphene film on dielectric can be obtained by removing copper fingers by a simple wet etching process. A creative approach to the cvd synthesis of ultra large area graphene based on selective joule heating was reported by kobayashi et al.
