C4 N4 Co1 Se4 Hg1

C₄N₄Co₁Se₄Hg₁ is an experimental quaternary semiconductor compound combining carbon nitride, cobalt, selenium, and mercury phases. This is a research-stage material in the chalcogenide semiconductor family, synthesized to explore novel optoelectronic and photocatalytic properties rather than established for commercial production. Interest in this composition stems from the potential to tune bandgap and carrier dynamics by combining transition metals (Co) with post-transition elements (Hg) in a nitride-selenide matrix, positioning it as a candidate for next-generation photocatalysis, photodetection, or energy conversion applications if stability and synthesis scalability challenges can be addressed.
