KYO2
KYO2 is a stable, insulating potassium yttrium oxide used in fundamental materials science research.

About KYO2
KYO2 is a chemically distinct oxide composed of potassium, yttrium, and oxygen. As a thermodynamically stable compound residing on the convex hull, it represents a robust phase that maintains structural integrity under standard conditions.
This material functions as a wide-band-gap insulator, a characteristic that makes it an interesting candidate for specialized electronic and optical applications. Its structural diversity, evidenced by multiple reported configurations, highlights its versatility in solid-state chemistry.
Key Properties
Cross-validated computational properties for KYO2, 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.
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.
