Graphene synthesis by cvd on copper substrates.

Graphene is needed 1. The graphene was grown using chemical vapor deposition cvd. Various measurements showed predominantly uniform monolayer graphene. During cvd a reaction occurs between the copper substrate and the graphene that create a high level of hydrostatic compression coupling the graphene to the substrate.

Highly uniform monolayer graphene synthesis via a facile pretreatment of copper catalyst substrates using an ammonium persulfate solution hyunhak jeong ab wang taek hwang a younggul song a jae keun kim a youngrok kim a joshua hihath b seungjun chung c and takhee lee a the demand for large area high quality synthesis of graphene with chemical vapor deposition cvd has. 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. 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. A creative approach to the cvd synthesis of ultra large area graphene based on selective joule heating was reported by kobayashi et al.
