Predicting lasing thresholds and output power far above threshold in...

  8. Nano Carbon: From ballistic transistors to atomic drumheads

    14 May 2008 | | Contributor(s):: Paul L. McEuen

    Carbon takes many forms, from precious diamonds to lowly graphite. Surprisingly, it is the latter that is the most prized by nano physicists. Graphene, a single layer of graphite, can serve as an impenetrable membrane a single atom thick. Rolled up into a nanometer-diameter cylinder--a carbon...
