C2SeN2

C2SeN2 is an experimental ceramic compound containing carbon, selenium, and nitrogen—a member of the emerging family of ternary nitride and chalcogenide ceramics. This material is primarily of research interest for applications requiring wide bandgap semiconductors or advanced refractory properties, as the selenium incorporation and ternary composition suggest potential for photonic, thermal management, or extreme environment applications. Compared to conventional binary nitrides or oxides, such mixed-anion ceramics remain largely in development stages but offer design flexibility for tailoring properties at the atomic level.
