Graphene, a single-atom-thick lattice of carbon atoms, is often touted as a replacement for silicon in electronic devices due to its extremely high conductivity and unbeatable thinness. But graphene is not the only two-dimensional material that could play such a role.
University of Pennsylvania researchers have made an advance in manufacturing one such material, molybdenum disulphide. By growing flakes of the material around "seeds" of molybdenum oxide, they have made it easier to control the size, thickness and location of the material.
