BaSrO2
BaSrO2 is a metastable semiconducting oxide compound consisting of barium, strontium, and oxygen.
About BaSrO2
BaSrO2 is a semiconducting oxide composed of barium, strontium, and oxygen. As a metastable phase, it represents a unique structural configuration within the alkaline earth oxide family, offering researchers a distinct electronic profile compared to more common, stable binary oxides.
Its existence as a metastable compound makes it a subject of interest for fundamental studies in materials synthesis and phase stability. By investigating such materials, scientists gain insights into the complex coordination environments possible when combining different alkaline earth metals in an oxide lattice.
Key Properties
Cross-validated computational properties for BaSrO2, 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.
