Graphene (1 of 2) (IMAGE) Rice University Caption Rice University researchers used computer models to determine the best way to disperse heat produced by microelectronic devices using gallium nitride semiconductors and diamond. A patterned surface and a layer of atom-thick graphene helped transport phonons from the semiconductor to the heat sink.
