BrO2
BrO2 is a metallic, metastable bromine oxide that is primarily studied for its complex structural properties in fundamental chemical research.
About BrO2
Bromine dioxide is a reactive inorganic compound composed of bromine and oxygen. It is characterized by its metallic electronic nature, distinguishing it from typical insulating oxides, and it exists as a metastable phase that sits above the thermodynamic hull.
Due to its inherent instability, this compound is primarily of interest in fundamental chemical studies and atmospheric science research. Its complex structural landscape is evidenced by the extensive number of configurations reported across various materials databases.
Key Properties
Cross-validated computational properties for BrO2, 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.
