Graphene, on or off?

This month has seen Texas Instruments give further insights into their CVD work on the growth of graphene and fabrication of FETs. IBM have produced a graphene transistor running at 100GHz and UCLU one with a cut of frequency of 300GHz. However, as real world applications become more feasible, the IBM group has highlighted the issues associated with the difficulty of turning off a graphene FET. Residual leakage currents will generate heat and the inability to always detect the difference between an open and a closed gate are clearly worrying IBM.
