Graphene: Pushing the boundaries.

The article discusses how cunning refinements can improve electron transport in polycrystalline graphene by pushing the boundaries and the sizes of the grains. Researchers are facing challenges in the nucleation stage and growth of the material on metal surfaces like copper. Several approaches that affect the creation of large single crystals are also discuss such as using polycrystalline copper, surface energy minimization, and the electronic properties of graphene.
