IBM showed off its engineering prowess by demonstrating a 100GHz Graphene transistor reports EE Times.
Graphene is expected to eventually replace the silicon based transitor but thus far has not been shown off operating in “normal” conditions. “There are all kinds of extraordinary claims being made every day for graphene semiconductors, but this is the first demonstration of a radio frequency graphene transistor that was made under technologically relevant conditions and scale,” said IBM Fellow Phaedon Avouris.
Graphene based transistors double performance compared to a silicon based transistors and IBM expect graphene transistors to eventually hit 1THz. Makes the GigaHertz race sound quite pedestrian.
