CVD Graphene

Graphene is a two-dimensional nanomaterial  which is composed of monolayers of sp2-bounded carbon atoms. Graphene has drawn considerable attention in both academic and industry area for various potential applications including semiconductors, energy storage devices, and sensors due to their physical properties such as high room-temperature mobility, high thermal conductivity. Obtaining single layer graphene or few-layer graphene by adhesive tape or cleavage methods is not practical because these methods provide only limited opportunity for scaling up the graphene. However, the chemical vapor deposition (CVD) process has been explored to synthesis large size single crystals and uniform films of monolayer graphene and bilayer graphene.  CVD is a method to produce graphene  which is fast, cheap and scalable. According to the experiences of graphene synthesis, it is well known that the growth of graphene is much easier from what is called ‘seed’. Chemical Vapor Depositio...
