Niobium nitride is a compound of niobium and nitrogen with the chemical formula NbN. At low temperatures, niobium nitride becomes a superconductor, and is used in detectors for infrared light.
Additional recommended knowledge
Niobium nitride's main use is as a superconductor. Detectors based on it can detect a single photon in the 3-10 micrometer section of the infrared spectrum, which is important for astronomy and telecomunications. It can detect changes up to 25 gigahertz.
Niobium nitride is also used in absorbing anti-reflective coatings.
