About Silver(I) fluoride
Silver(I) fluoride is a distinct inorganic compound composed of silver and fluorine. As a thermodynamically stable member of the silver halide family, it occupies a unique position on the convex hull, indicating robust structural integrity under standard conditions. Its metallic electronic character sets it apart from many other typical halide insulators, making it a subject of significant interest in condensed matter research. With a vast array of reported structures across multiple databases, it remains one of the most thoroughly documented silver-based compounds. Its behavior is critical for understanding the interplay between transition metal cations and highly electronegative anions in solid-state chemistry.
Key Properties
Cross-validated computational properties for Silver(I) fluoride, aggregated across 5 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of AgF. Tight agreement means computed properties can be trusted without re-running calculations.
