Episode 3: The Semiconductor Whisperer

In this third episode of DARPA’s podcast series, Voices from DARPA, join program manager Dan Green, as he discusses the Agency’s innovation-catalyzing roles in the Age of Semiconductors. For Green, silicon, the celebrity high-tech material of our times, is only one species in what he views as a semiconductor zoo. For his part, Green, who works in the Agency’s Microsystems Technology Office, has been overseeing DARPA’s efforts to usher the compound semiconductor, gallium nitride (or GaN), beyond its already transformative role in the world of LED lighting into a range of electronic and radiofrequency applications important for national security contexts--among them electronic warfare, radar, and communications--and eventually into an empowering variety of applications in the civilian world.
