KLaS2
KLaS2 is a stable, semiconducting ternary sulfide compound composed of potassium, lanthanum, and sulfur.
About KLaS2
KLaS2 is a ternary sulfide compound that exhibits semiconducting electronic behavior. As a thermodynamically stable phase residing on the convex hull, it represents a robust structural arrangement of potassium, lanthanum, and sulfur atoms.
This material is of significant interest in solid-state chemistry due to its well-defined crystalline nature. Its stability and electronic profile make it a subject of ongoing investigation for researchers looking to expand the library of functional sulfide materials.
Key Properties
Cross-validated computational properties for KLaS2, 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.
