Abstract :
Graphene devices are showing amazing flexibility, and not just the mechanical kind. Researchers at Rice University and the University of California, Riverside, recently demonstrated an amplifier, based on a single graphene transistor, that can do the job of three different amplifiers. The device could lead to smaller, lower-power analog circuits, such as Bluetooth radios, they say. Separately, scientists at IBM are developing a type of graphene device that can be reconfigured, on the fly, into six different logic gates. Despite this, engineers agree that practical graphene logic is many years away.
