Suspended Graphene with Thin Film (IMAGE)
Caption
In a vacuum, a suspended sheet of one-atom-thick graphene (brown lattice) could be manipulated to create a liquid film (atoms in dark blue) that stops growing at a thickness between 3 and 50 nanometers. By stretching the graphene, doping it with other atoms, or applying a weak electrical field nearby, the University of Vermont researchers who made the discovery have evidence that the number of atoms in an ultra-thin film can be controlled.
