Method to Grow Large Single-Crystal Graphene Could Advance Scalable 2-D Materials

Caption

In a controlled environment, the fastest-growing orientation of graphene crystals overwhelms the others and gets "evolutionarily selected" into a single crystal, even on a polycrystalline substrate, without having to match the substrate's orientation. An Oak Ridge National Laboratory-led team developed the novel method that produces large, monolayer single-crystal-like graphene films more than a foot long.
