Na3SbS3
Na3SbS3 is a stable semiconducting ternary sulfide compound containing sodium, antimony, and sulfur.
About Na3SbS3
Na3SbS3 is a ternary sulfide compound composed of sodium, antimony, and sulfur. As a thermodynamically stable material situated on the convex hull, it represents a robust phase within its chemical system, characterized by a semiconducting electronic nature that makes it a subject of interest for solid-state research.
Its structural diversity is evidenced by multiple reported configurations across various databases. This complexity suggests a flexible lattice arrangement, which is a key factor for investigators looking to understand how atomic positioning influences the electronic behavior of complex chalcogenides.
Key Properties
Cross-validated computational properties for Na3SbS3, 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.
