IBM hits graphene transistor breakthrough

Summary:IBM Research plans to announce that it has demoed a radio-frequency graphene transistor with the highest frequency so far

IBM Research on Friday will announce that it has demonstrated a radio-frequency graphene transistor with the highest frequency — 100GHz — so far.

Graphene is a special form of graphite, consisting of a layer of carbon atoms packed in honeycomb lattice. Its properties could lead to faster transistors.

IBM's paper, which will be published in Science, details how the latest graphene breakthrough could enable new communications devices and electronics. The paper was penned by Phaedon Avouris, IBM Fellow and manager of the company's nanometre scale science and technology research team.
