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.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
