Scientists tout discovery of non-toxic IR semiconductors

It’s a discovery that’s a bit difficult for the novice to understand, but it could lead to improved technology and a cleaner environment. To begin with, many existing infrared semiconductors capable of emitting infrared radiation (i.e., direct transition semiconductors) — contain toxic chemical elements, such as cadmium and tellurium. Secondly, infrared wavelengths have been used […]
