Exeter researchers have recently reported a new method to use graphene to produce photodetectors, which they feel could revolutionize the manufacturing of vital safety equipment, such as radiation and smoke detection units.
Researchers have studied how light can be used to observe the quantum nature of an electronic material. They captured light in graphene and slowed it down to the speed of the material’s electrons. Then electrons and light started to move in concert, manifesting their quantum nature at such large scale that it could observed with a special type of microscope.
