B2O
B2O is a metallic, structurally complex boron oxide that is generally considered thermodynamically unstable.
About B2O
B2O is a boron-oxygen compound characterized by its metallic electronic nature. Despite its simple stoichiometry, it exhibits a high degree of structural complexity, as evidenced by the vast number of configurations reported across materials databases.
Because it sits above the thermodynamic hull, B2O is considered a metastable or unstable phase under ambient conditions. Its metallic character distinguishes it from typical insulating boron oxides, making it a subject of interest for researchers studying high-pressure phases and exotic bonding environments.
Key Properties
Cross-validated computational properties for B2O, aggregated across 4 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of B2O. Tight agreement means computed properties can be trusted without re-running calculations.
