KScO2
KScO2 is a thermodynamically stable, wide-band-gap insulating oxide containing potassium, scandium, and oxygen.
About KScO2
KScO2 is a stable ternary oxide composed of potassium, scandium, and oxygen. As a wide-band-gap insulator, it exhibits electronic characteristics typical of highly stable ionic compounds that occupy a position on the convex hull of thermodynamic stability.
This material is of interest to researchers investigating the structural diversity of scandium-based oxides. With multiple reported structures across major databases, it serves as a foundational subject for understanding phase stability and coordination chemistry in complex oxide systems.
Key Properties
Cross-validated computational properties for KScO2, 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.
