About FeBiSbS4
FeBiSbS4 is a quaternary sulfide compound composed of iron, bismuth, antimony, and sulfur. As a semiconducting material, it represents a complex arrangement of heavy metal cations coordinated with chalcogenide anions, which is a subject of interest in exploratory solid-state chemistry.
Because this compound sits above the thermodynamic hull, it is considered a metastable phase. Its existence in structural databases highlights the ongoing effort to synthesize and characterize complex multinary sulfides that may offer unique electronic properties despite their energetic instability.
Key Properties
Cross-validated computational properties for FeBiSbS4, 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.
