BaCaO2
BaCaO2 is a metastable, semiconducting ternary oxide consisting of barium, calcium, and oxygen.
About BaCaO2
BaCaO2 is a ternary oxide composed of barium, calcium, and oxygen. As a semiconducting material, it represents a complex arrangement of alkaline earth metals that has been the subject of significant structural investigation across multiple databases. Its electronic nature makes it a point of interest for researchers studying the fundamental properties of mixed-cation oxides. Because it is classified as a metastable phase, the synthesis and stabilization of BaCaO2 require precise control over processing conditions. This metastability often dictates its potential utility in specialized thin-film applications or as a precursor in the development of more complex ceramic systems.
Key Properties
Cross-validated computational properties for BaCaO2, 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.
