  • Mass-Producing Graphene American Scientist

    Simply heat the copper to about 1,000 degrees Celsius and expose it to the methane gas. Layers of graphene will form on the copper’s surface from the plentiful carbon atoms in the methane gas, a process called chemical vapor deposition (CVD). There are two big problems with this method: It takes a long time to make even a little graphene, and

  • Graphene Wikipedia

    Graphene was properly isolated and characterized in 2004 by Andre Geim and Konstantin Novoselov at the University of Manchester. They pulled graphene layers from graphite with a common adhesive tape in a process called either micromechanical cleavage or the Scotch tape technique. The graphene flakes were then transferred onto thin silicon dioxide (silica) layer on a silicon plate ("wafer").
