Niobium nitride (NbN) is a ceramic compound semiconductor belonging to the refractory metal nitride family, known for its high hardness, chemical stability, and metallic conductivity. It is primarily used in hard coatings for cutting tools, wear-resistant applications, and thin-film electronic devices, where its combination of hardness and electrical conductivity offers advantages over traditional ceramics. The material is also of interest in superconductor research and as a barrier/adhesion layer in microelectronic manufacturing due to its thermodynamic stability with both metals and semiconductors.
