BNL 13-07: Graphene-Boron Nitride Monolayer Heterostructures

BNL Reference Number: BNL 13-07

Summary

Both graphene (a form of carbon) and hexagonal boron nitride form two-dimensional sheets of monolayer thickness under the right growth conditions. They exhibit the same crystal structure, have nearly the same lattice dimensions, and are isoelectronic. Nevertheless, their electronic band structures are different enough to promise interesting functional properties if integrated into two-dimensional heterostructures. The inventive methods described here allow for creating such heterostructures and controlling the interfacial properties between domains of the two materials. This, in turn, allows the exploitation of emergent electrical, optical, and magnetic properties of the resulting novel system.
