Paper Abstract

The requirement for long-range structure coherence and property uniformity for graphene-based electronics are crucial for their applications in electronics. Here, we briefly review our recent progress on synthesis of large-size graphene by seeded growth method. We demonstrate a seeded growth method which allows us to reduce the nucleation density in early stage of Chemical Vapor Deposition (CVD) leading to the production of low density of graphene grains and consequently achieve grain size of sub-centimeter. We further demonstrate that we can amplify the graphene grain size by limiting the second seeded growth only from the graphene seed edges. Moreover, we demonstrate that similar method can be used for the preparation of large-grain bilayer graphene flakes.
