Avalanche Photodiode Dupuis (IMAGE) Georgia Institute of Technology Research News Caption Researchers in Georgia Tech's School of Electrical and Computer Engineering work inside a hood that contains an electronic device probe station, which precisely measures the device characteristics of a new class of ultraviolet photodiode the researchers developed. They believe the photodiode could help meet the US military's pressing requirement for compact, reliable and cost-effective sensors to detect anthrax and other bioterrorism agents in the air.
