Synthetic Graphene

Very fast electronic circuits and flexible display screens; the promises of graphene are plenty. This material, which consists of a single layer of carbon atoms, is one of the fastest semiconductors. Since graphene was discovered in 2004, scientists have been looking frantically for ways to produce it as purely as possible. Only in its purest form can electrons move freely through the atomic lattice, a phenomenon called ballistic transport. In January researchers from the MMME and AS faculties described in Applied Physics Letters how they were able for the first time to demonstrate ballistic transport in synthetic graphene which they fabricated by chemical vapor deposition.
