Submission + - Graphene Transistors 10x faster than Silicon (technologyreview.com)
Asadullah Ahmad writes: IBM has created transistors made from carbon atoms, which operate at 100 gigahertz, while using a manufacturing process which is compatible with current semiconductor fabrication. With silicon close to its physical limits, graphene seems like a viable replacement until Quantum Computing gets to desktop.
Researchers have previously made graphene transistors using laborious mechanical methods, for example by flaking off sheets of graphene from graphite; the fastest transistors made this way have reached speeds of up to 26 gigahertz. Transistors made using similar methods have not equaled these speeds.
