KCO2
KCO2 is a semiconducting ternary compound of potassium, carbon, and oxygen that is considered a promising candidate for laboratory synthesis.
About KCO2
KCO2 is an intriguing inorganic compound composed of potassium, carbon, and oxygen. As a semiconducting material, it occupies a unique niche in solid-state chemistry, offering distinct electronic properties that differentiate it from common insulating oxides or metallic conductors. Its structural complexity is evidenced by a significant number of reported configurations across major databases.
Because it is identified as a near-hull material, KCO2 is considered a prime candidate for experimental synthesis. Its stability profile suggests that while it may not be the most common phase, it remains a viable target for researchers investigating novel ternary oxides and potential functional materials for electronic or catalytic applications.
Key Properties
Cross-validated computational properties for KCO2, aggregated across 4 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.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
