· Ca3N2

Calcium nitride (Ca₃N₂) is an inorganic ceramic semiconductor compound belonging to the metal nitride family, characterized by ionic bonding between calcium cations and nitrogen anions. It is primarily investigated in research and early-stage development contexts for applications requiring wide bandgap semiconductors, particularly in optoelectronics and high-temperature electronics where traditional semiconductors degrade; the material offers potential advantages over conventional alternatives due to its thermal stability and wide energy gap, though industrial adoption remains limited compared to established nitride semiconductors like GaN and AlN.
