Its wide-band-gap profile suggests potential utility in optoelectronic or dielectric applications where electrical insulation is a primary requirement. The compound is recognized for its structural diversity, with multiple reported configurations across crystallographic databases.
Key Properties
Cross-validated computational properties for Br3CaCs, 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.
