Scientist predicts that Graphene will skip FET and jump straight to quantum devices

Georgia Tech Professor Walt de Heer predicts that Graphene will not follow the model of using standard field-effect transistors, but will pursue devices that use ballistic conductors and quantum interference. The Professor's research team hopes to show a basic quantum interference switch within a year.

Taking advantage of the wave properties will allow electrons to be manipulated with techniques similar to optical control, for instance switching may be carried out using interference - separating beams of electrons and then recombining them in or out of phase to switch the signal.
