I4Sb4Se4
This compound is a complex chalcogenide-halide material composed of antimony, selenium, and iodine. It is primarily studied in materials science research for its potential semiconducting properties and its structural characteristics within the broader family of antimony-based chalcogenides.
Key Properties
Cross-validated computational properties for I4Sb4Se4, 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.
