New kind of high-temperature photonic crystal could someday power everything from smartphones to spacecraft
New kind of high-temperature photonic crystal could someday power everything from smartphones to spacecraft: "A team of MIT researchers has developed a way of making a high-temperature version of a kind of materials called photonic crystals, using metals such as tungsten or tantalum. The new materials — which can operate at temperatures up to 1200 degrees Celsius — could find a wide variety of applications powering portable electronic devices, spacecraft to probe deep space, and new infrared light emitters that could be used as chemical detectors and sensors."
