BaMgO2
BaMgO2 is a metastable, wide-band-gap insulating oxide containing barium and magnesium.
About BaMgO2
BaMgO2 is an insulating oxide composed of barium, magnesium, and oxygen. As a wide-band-gap material, it exhibits electronic properties characteristic of dielectric compounds, making it a subject of interest for fundamental solid-state studies.
Although it is classified as a metastable phase, the compound has been identified across multiple structural databases. This suggests a complex energy landscape that researchers investigate to understand the stability limits of alkaline earth metal oxides.
Key Properties
Cross-validated computational properties for BaMgO2, 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.
