TR10: Graphene Transistors

March/April 2008. By Kevin Bullis

Walter de Heer, a professor of physics at Georgia Tech, explains how graphene, a form of carbon consisting of layers one atom thick, can be used to make ultrafast transistors. Most recently, de Heer has made experimental arrays of hundreds of graphene transistors on a chip. De Heer talks about both the promise of this new electronic material and the challenges of competing against conventional silicon electronics.
