Introduction Niobium nitride (NbN) is one of the most influential transition-metal nitrides used in modern thin-film technology. Known for its high superconducting transition temperature (Tc ≈ 16 K), superior hardness, excellent chemical stability, and metallic conductivity, NbN plays a critical role in next-generation electronics, photonics, quantum devices, and protective coatings. As a sputtering target, NbN […]
