C2 N4

C₂N₄ is an experimental carbon nitride semiconductor compound consisting of carbon and nitrogen atoms in a 2:4 stoichiometric ratio. This material belongs to the emerging class of carbon-based semiconductors and represents a theoretical structure within the broader family of graphitic carbon nitrides (g-C₃N₄), which have attracted significant research interest for their tunable bandgap and potential as alternatives to traditional inorganic semiconductors. While still primarily studied at the research level rather than in widespread industrial production, C₂N₄ is notable for its potential combination of semiconductor properties with the environmental advantages of carbon-nitrogen chemistry, positioning it as a candidate material for next-generation optoelectronic and photocatalytic applications where performance and sustainability both matter.
