(Phys.org) —Despite graphene's many impressive properties, its lack of a bandgap limits its use in electronic applications. In a new study, scientists have theoretically shown that a bandgap can be opened in graphene by ...
(Phys.org) —Two teams of researchers, one working in Saudi Arabia, the other in Spain, have discovered independently that adding vibrations to a graphene surface allows for more efficient conversion of photons to plasmons. ...
Concentric hexagons of graphene grown in a furnace at Rice University represent the first time anyone has synthesized graphene nanoribbons on metal from the bottom up—atom by atom.
