Bilayer Graphene Creates Fast, Sensitive Photodetector
Innovation promises better biochemical weapons detection, body scanners and new instruments for studying dark energy and the structure of the universe.
Researchers at the Center for Nanophysics and Advanced Materials of the Univ. of Maryland have developed a new type of hot electron bolometer — a sensitive detector of infrared light — that can be used in a huge range of applications from detection of chemical and biochemical weapons from a distance and use in security imaging technologies such as airport body scanners, to chemical analysis in the laboratory and studying the structure of the universe through improved telescopes.
