About KS3
KS3 is a potassium-sulfur compound that exhibits semiconducting electronic properties. As a thermodynamically stable phase located on the convex hull, it represents a robust configuration within the potassium-sulfur binary system.
The material is characterized by significant structural complexity, evidenced by a high number of reported structures in crystallographic databases. This structural variety makes it a subject of interest for fundamental studies in solid-state chemistry and materials design.
Key Properties
Cross-validated computational properties for KS3, aggregated across 2 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.
