Since its inception, scientists have tried to exploit graphene to produce nano-sized electronics. However, since graphene is only an atom thick, all atoms are exposed to the outside world, and even small amounts of defects and impurities impede its properties. Now, Graphene Flagship researchers at the Technical University of Denmark (DTU) solved this problem by protecting graphene with insulating layers of hexagonal boron nitride, another two-dimensional material with insulating properties.
