We have performed pioneering work on the growth and properties of graphene and other two-dimensional (2D) crystals on metal substrates. Our research has shown that graphene can be grown with very high quality and macroscopic monocrystalline domains on transition metals. Recent work has extended this capability to other 2D materials, such as hexagonal boron nitride (h-BN). The availability of different 2D materials offers the prospect of combining them in engineered heterostructures, either in the form of superlattices of alternating monolayer membranes or by interfacing them within a single, atomically thin sheet. We are actively engaged in identifying pathways for synthesizing such engineered materials, and exploring how new properties emerge from the integration of 2D components.
