About K3SO4F
K3SO4F is an inorganic compound characterized by its wide-band-gap insulating electronic nature. Its composition suggests a structural complexity that places it as a subject of interest for researchers investigating stable, non-conducting crystalline frameworks.
Due to its position near the thermodynamic hull, this material is considered a viable candidate for experimental synthesis. The existence of multiple reported structures across various databases highlights its significance as a target for structural characterization and materials discovery.
Key Properties
Cross-validated computational properties for K3SO4F, 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.
