    Duke Engineers Trap Light in a 10-Nanometer Gap to Build World's Fastest Thermal Detector — 125 Trillionths of a Second

    Using silver nanocubes arranged just 10 nanometers above a gold surface to concentrate light through plasmonics, a Duke University team created a room-temperature photodetector operating at 2.8 gigahertz — hundreds to thousands of times faster than any previous thermal sensor — with transformative potential for medical imaging, precision agriculture, and space exploration.
