Graphene just added another badge to its supermaterial sash.
New experiments show that this single layer of carbon atoms can transform electronic signals at gigahertz frequencies into higher-frequency terahertz signals — which can shuttle up to 1,000 times as much information per second.
Electromagnetic waves in the terahertz range are notoriously difficult to create, and conventional silicon-based electronics have trouble handling such high-frequency signals (SN: 3/28/09, p. 24). But graphene-based devices could. These future electronics would work much faster than today’s devices, researchers report online September 10 in Nature.
Physicist Dmitry Turchinovich of the…
