New study reveals graphenes now go monolayer and single crystalline

An international team of researchers, led by Distinguished Professor Rodney S. Ruoff (School of Natural Sciences) from the Center for Multidimensional Carbon Materials (CMCM), within the Institute for Basic Science (IBS) at UNIST, has reported a truly single layer (i.e., adlayer-free) large area graphene film on large area copper foils. This might seem like the latest in a series of seemingly similar declarations on single layer graphene. However, this achievement differs from other thousands of previous publications in that none of them had described truly single layer graphene over large area. Adlayers (bilayer or multilayer regions) have always been present in such films.
