Co2K12Se8
Co2K12Se8 is a semiconducting cobalt potassium selenide that is theoretically stable enough to be synthesized for materials research.
About Co2K12Se8
Co2K12Se8 is a complex ternary selenide composed of cobalt, potassium, and selenium. As a semiconducting material, it represents a unique structural arrangement within its chemical family that warrants further investigation for its electronic properties.
Because it sits near the thermodynamic hull, this compound is considered a promising candidate for experimental synthesis. Its existence across multiple structural databases highlights its significance as a stable or metastable phase in the cobalt-potassium-selenium system.
Key Properties
Cross-validated computational properties for Co2K12Se8, aggregated across 3 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
