BrN
BrN is an unstable, metallic compound composed of bromine and nitrogen that is frequently studied in computational structural databases.
About BrN
BrN is a binary compound consisting of bromine and nitrogen. It exhibits metallic electronic character, a notable feature for this combination of elements, and is categorized as a material that sits above the thermodynamic hull, suggesting it is inherently unstable under standard conditions. Despite its instability, the compound is of significant interest in computational materials science due to the high volume of structural data available. Researchers track its various configurations to better understand the bonding dynamics between halogens and pnictogens.
Key Properties
Cross-validated computational properties for BrN, 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.
