About KCuS
KCuS is a ternary sulfide compound that exhibits semiconducting electronic behavior. As a thermodynamically stable phase residing on the convex hull, it represents a robust material configuration within its chemical system.
The compound is characterized by significant structural diversity, with multiple reported configurations across various databases. This structural flexibility makes it a subject of interest for researchers investigating the fundamental properties of copper-based chalcogenides.
Key Properties
Cross-validated computational properties for KCuS, 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.
