· W2 N4

W2N4 is a nitride-based semiconductor compound in the tungsten-nitrogen chemical family, representing a material system under active research for advanced electronic and photonic applications. Tungsten nitride semiconductors are investigated for their potential in high-temperature electronics, power devices, and optoelectronic components where thermal stability and wide bandgap properties are advantageous over conventional semiconductors. This material family is particularly relevant for researchers exploring next-generation wide-bandgap semiconductor alternatives to gallium nitride (GaN) and silicon carbide (SiC) in demanding thermal and high-power environments.
