Graphene's high-speed seesaw
Manchester, UK (SPX) May 03, 2013
Writing in Nature Communications, the researchers report the first graphene-based transistor with bistable characteristics, which means that the device can spontaneously switch between two electronic states. Such devices are in great demand as emitters of electromagnetic waves in the high-frequency range between radar and infra-red, relevant for applications such as security systems and medical imaging. Bistability is a common phenomenon - a seesaw-like system has two equivalent states and small p ... read more
