CVD Growth of Large-Size Single Crystal Graphene and 3D Graphene Macrostructures

摘要

Large-size single crystal graphene grains are important since grain boundaries are believed to markedly degrade its quality and properties. However, graphene films prepared so far are usually stitched together from nanometer to micrometer-size grains. At the same time, integration of individual two-dimensional graphene into macroscopic structures is essentially important for many applications of graphene. But graphene-based composites from chemically-derived graphene sheets suffer from poor electrical conductivity.
