IBM: Graphene wont be the next Silicon. Might make good hybrid chips though

IBM has revealed that graphene can't yet fully replace silicon inside CPUs, as a graphene transistor can't actually be completely switched off.

In an interview for a forthcoming Custom PC feature about chip-building materials, Yu-Ming Lin from IBM Research - Nanometer Scale Science and Technology told us that 'graphene as it is will not replace the role of silicon in the digital computing regime.'

Last year, IBM demonstrated a graphene transistor running at 100GHz, claiming that the technology could be used to manufacture 'zippy computer chips' in the years to come. The story, along with news that researchers at the UCLU had produced a graphene transistor with a cut-off frequency of 300GHz, prompted all sorts of predictions of silicon marching towards its demise, making way for a graphene-based future with 1THz (one terahertz, or 1,000GHz) CPUs.
