A sheet of carbon atoms, called graphene, could soon replace silicon in transistors. The enhanced conductivity and extremely small size of the “nano-ribbons” will represent definite advantages for this new technology.

Transistors more than four times smaller than the tiniest silicon ones and potentially more efficient can be made using sheets of carbon just one-tenth of a nanometre thick, research shows. Unlike other experimental nanoscopic transistors, the new components require neither complex manufacturing nor cryogenic cooling.
