About Be4Cs8F16
Be4Cs8F16 is a complex fluoride compound composed of beryllium, cesium, and fluorine. As a thermodynamically stable phase located on the convex hull, it represents a well-defined structural arrangement within its chemical system.
Characterized as a wide-band-gap insulator, this material exhibits electronic properties typical of highly stable ionic solids. Its existence as a distinct crystalline phase makes it a subject of interest for fundamental studies in solid-state chemistry and materials science.
Key Properties
Cross-validated computational properties for Be4Cs8F16, 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.
