LiS2Ta
LiS2Ta is a stable semiconducting ternary sulfide compound composed of lithium, sulfur, and tantalum.
About LiS2Ta
LiS2Ta is a ternary lithium tantalum sulfide that exhibits semiconducting electronic behavior. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement of lithium, sulfur, and tantalum atoms. Its stability and electronic profile make it an intriguing subject for fundamental research into complex chalcogenide materials. The compound is characterized by a well-defined structural framework that has been documented across multiple databases.
Key Properties
Cross-validated computational properties for LiS2Ta, 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.
