Graphene Oscillator Circuitry 
reaches the Gigahertz Range


 




Many people think that the future of electronics is going to include graphene, a sheet of carbon just a single atom thick that allows electrons to move through as if they were massless. Some of the first electronic devices involving graphene have already been built in the lab, but graphene presents its own challenges. It's not naturally a semiconductor, and most devices based on it have had poor performance due to current leakage. Now, researchers have put together a simple graphene-based test device that can operate at over 1.2GHz, and they used it as the basis for an all-graphene frequency mixer. Although the performance still isn't good enough for real-world use, it's a major step in the right direction.
