About BaNa2O2
BaNa2O2 is a ternary oxide compound composed of barium, sodium, and oxygen. As a semiconducting material, it represents a unique intersection of alkaline earth and alkali metal chemistry, offering distinct electronic properties that differentiate it from simpler binary oxides. The compound is characterized as metastable, which makes it a subject of significant interest for researchers studying phase stability and synthesis pathways. Its existence across multiple reported structures highlights the complexity of its bonding environment.
Key Properties
Cross-validated computational properties for BaNa2O2, 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.
