The new transistor achieves a record high-switching performance which will make our future electronic devices - such as PDAs and computers - even more functional and high-performance.
In a paper to be published in Electronics Letters on 3 February 2011, Dr Zakaria Moktadir of the Nano research group at the University's School of Electronics and Computer Science (ECS) describes how his research into graphene, a material made from a single atomic layer of carbon, arranged in a two-dimensional honeycomb structure, led to the development of graphene field effect transistors (GFETs) with a unique channel structure at nanoscale.
According to Dr Moktadir, in the context of electronics, graphene could potentially replace or at least be used side by side with silicon integrations.
"CMOS (Silicon Complementary Metal-Oxide- Semiconductor) downscaling is reaching its limits and we need to find a suitable alternative," he said. "Other researchers had looked at graphene as a possibility, but found that one of the drawbacks was that graphene's intrinsic physical properties make it difficult to turn off the current flow."
