Electronic life on the edge: Scientists discover the edge states of graphene nanoribbons Posted: 08 May 2011 10:49 AM PDT Scientists have used new techniques to confirm the existence of long-predicted edge states in graphene nanoribbons, opening new prospects for characterizing and controlling the electronic, spintronic, magnetic, and optical properties of nanoscale devices.

Toward optical computing in handheld electronics: Graphene optical modulators could lead to ultrafast communications Posted: 08 May 2011 10:49 AM PDT Researchers have shown that graphene, a one-atom-thick layer of crystallized carbon, can be tuned electrically to modify the amount of photons absorbed. This ability to switch light on and off is the fundamental characteristic of a network modulator, opening the door to optical computing in handheld electronics.
