KLaO2
KLaO2 is a stable, wide-gap insulating oxide compound composed of potassium, lanthanum, and oxygen.
About KLaO2
KLaO2 is a complex oxide composed of potassium, lanthanum, and oxygen. As a thermodynamically stable compound residing on the convex hull, it represents a robust structural arrangement that is well-defined within materials databases.
This material functions as a wide-gap insulator, characterized by its electronic configuration that prevents electrical conduction. Its stability and insulating nature make it an interesting candidate for fundamental studies in solid-state chemistry and oxide-based material design.
Key Properties
Cross-validated computational properties for KLaO2, 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.
