Synthesis of Few-layer (Graphene on a Ni Substrate by Using DC Plasma Enhanced Chemical Vapor Deposition (PE-CVD)

In this work, few-layer graphene (FLG) was successfully grown on polycrystalline Ni a large scale by using DC plasma enhanced chemical vapor deposition (DC PE-CVD), which may serve as an alternative route in large-scale graphene synthesis. The synthesis time had an effect on the quality of the graphene produced. The applied DC voltage, on the other hand, influenced the minimization of the defect densities in the graphene grown. We also present a method of producing a free-standing polymethyl methacrylate (PMMA)/graphene membrane on a FeCl(3(aq)) solution, which could then be transferred to the desired. substrate.
