SiS2
Silicon disulfide · Silicon(IV) sulfide
Silicon disulfide is a stable, insulating inorganic compound composed of silicon and sulfur that is widely studied for its structural properties.
About Silicon disulfide
Silicon disulfide is a thermodynamically stable compound that exists as a wide-gap insulator. Its unique structural chemistry is highlighted by its presence on the convex hull, indicating significant stability under standard conditions.
This material is a subject of extensive structural investigation, with numerous reported configurations across scientific databases. Its insulating electronic character and distinct bonding architecture make it a valuable subject for research into silicon-sulfur chemistry and specialized materials development.
Key Properties
Cross-validated computational properties for Silicon disulfide, 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.
