Researchers at the University of Central Florida (UCF) have developed a graphene-based transistor that could someday be used in computers that are 1,000 times faster and use one-100th of the power of conventional computer systems.
Silicon-based transistors are approaching their limit in terms of how small they can become, so researchers around the world are experimenting with next-generation transistors that are based on a ribbon of graphene.
The UCF researchers found by applying a magnetic field to a graphene ribbon, they could change the resistance of current flowing through it.
The researchers say the device's magnetic field is controlled by increasing or decreasing the current through adjacent carbon nanotubes.
The team notes a cascading series of graphene transistor-based logic circuits could increase clock speeds to near-terahertz range, resulting in devices that are small and substantially more efficient.
