IBM Scientists Develop World's Fastest Graphene Transistor
Date added: 19 Dec 2008
"IBM Scientists from the company's T. J. Waston Research Center have demonstrated the operation of a graphene field-effect transistors at GHz frequencies. Graphene is a special form of graphite, consisting of a single layer of carbon atoms packed in honeycomb lattice, similar to an atomic scale chicken wire. With a top gate deisgn and a gate length 150 nm, the team has achieved a cut-off frequency of 26 GHz for graphene transistors; the highest frequencies reported so far using this novel non-silicon electronic material.
