Engineers from the UCLA Samueli School of Engineering have invented a new type of photodetector, using graphene, one of science’s most versatile materials, that can work with more types of light than its current state-of-the-art counterparts. The device also has superior sensing and imaging capabilities. “Our photodetector could extend the scope and potential uses of photodetectors in imaging and sensing systems,” said ECE Professor, Mona Jarrahi, who led the study. “It could dramatically improve thermal imaging in night vision or in medical diagnosis applications where subtle differences in temperatures can give doctors a lot of information on their patients. It could also be used in environmental sensing technologies to more accurately identify the concentration of pollutants.”
