BeCuBr
BeCuBr is a semimetallic, thermodynamically unstable inorganic compound composed of beryllium, copper, and bromine that is primarily studied for its structural diversity.

About BeCuBr
BeCuBr is a complex inorganic compound composed of beryllium, copper, and bromine. Its electronic character is defined as semimetallic, placing it in a unique position where its conductive properties are influenced by its specific atomic arrangement. Given its status as a material that sits above the thermodynamic hull, it is considered inherently unstable under standard conditions. The compound has attracted significant attention in computational materials science, as evidenced by its presence across multiple structural databases. Researchers study its various configurations to understand the fundamental interactions between these distinct elements, which is essential for characterizing its potential behavior in theoretical high-energy states.
Key Properties
Cross-validated computational properties for BeCuBr, 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.
