O4S8Sb8
O4S8Sb8 is a semiconducting antimony sulfur oxide that is theoretically stable enough to be synthesized in a laboratory setting.
About O4S8Sb8
O4S8Sb8 is a complex inorganic compound composed of antimony, sulfur, and oxygen. As a semiconducting material, it occupies a unique position in solid-state chemistry, offering distinct electronic properties that arise from the interplay of its constituent chalcogen and pnictogen elements.
This material is considered to be near the thermodynamic hull, suggesting it is a viable candidate for experimental synthesis. Its existence within structural databases highlights its potential interest for researchers exploring novel semiconducting phases that deviate from traditional binary or ternary systems.
Key Properties
Cross-validated computational properties for O4S8Sb8, 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.
