Graphene is a material that invites superlatives. It has been much in the news recently, especially following the 2010 Nobel Prize to Andre Geim and Konstantin Novaselov for their ‘groundbreaking experiments’ on graphene. A two-dimensional sheet of carbon atoms linked in a hexagonal lattice, just one atom thick, it is the thinnest known material, is harder than diamond and stronger than steel, while still very stretchable (by up to 20%), has an electrical conductivity higher than copper, and has an exceptionally high thermal conductivity.
