Sc2S3
Sc2S3 is a thermodynamically stable, semiconducting inorganic sulfide compound.
About Sc2S3
Sc2S3 is a thermodynamically stable sulfide compound that exhibits semiconducting electronic behavior. As a member of the scandium-sulfur system, it represents a significant phase that sits securely on the convex hull, indicating robust stability under standard conditions.
With a high degree of structural diversity reported across multiple databases, this material is a subject of interest for researchers investigating complex chalcogenide systems. Its semiconducting nature makes it a candidate for specialized electronic and optoelectronic applications where stable, non-metallic inorganic materials are required.
Key Properties
Cross-validated computational properties for Sc2S3, 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.
