Abstract

Spatially ordered arrays of single crystal graphene grains are synthesized by locally controlling nucleation on polycrystalline Cu using chemical vapor deposition. The grains can be transferred on an arbitrary substrate for further characterization and device fabrication. This offers a way to potentially fabricate graphene-based devices by regular microelectronic processes free of graphene grain boundaries and with more reliable performances.
