InS2
InS2 is a metallic indium sulfide compound known for its structural complexity and metastable nature.
About InS2
InS2 is a metallic compound composed of indium and sulfur. Its electronic character distinguishes it from many common semiconducting sulfides, marking it as a unique candidate for fundamental studies in condensed matter physics. Despite its metallic nature, the material exhibits a complex structural landscape with numerous reported configurations across various databases. Its thermodynamic profile indicates that it sits above the stability hull, suggesting it is a metastable phase that requires specific synthesis conditions to realize. This inherent instability makes it a subject of significant interest for researchers investigating phase transitions and high-pressure materials science.
Key Properties
Cross-validated computational properties for InS2, aggregated across 4 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.
