Nano carbon: from solar cells to atomic drums
Abstract: Carbon takes many forms, from precious diamond to lowly graphite. Surprisingly, it is the latter that is the most prized by nanoscientists. Graphene, a single layer of graphite, is the first truly 2D material. It is incredibly strong, robust, and impenetrable to gases, in spite of being only a single atom thick. Equally fascinating are nanometer-diameter cylinders of graphene--carbon nanotubes. These make great 1D transistors, quantum dots, and nanoguitar strings. In this talk, I will review some of our group’s recent results on these remarkable materials, from measurements of next-generation nanotube solar cells to playing an atomic drum that is one atom thick.
