SbO2F
SbO2F is a semiconducting antimony oxyfluoride that is theoretically stable and of interest for its structural diversity.
About SbO2F
SbO2F is a complex inorganic oxyfluoride that exhibits semiconducting electronic properties. Its composition, balancing antimony with oxygen and fluorine, places it in a unique category of materials that bridge the gap between traditional oxides and fluorides.
The compound is considered near-hull in terms of thermodynamic stability, suggesting it is a viable candidate for experimental synthesis. With multiple reported structural configurations across various databases, it represents a versatile subject for study in solid-state chemistry.
Key Properties
Cross-validated computational properties for SbO2F, 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.
