Ca3SnS5
Ca3SnS5 is a semiconducting ternary sulfide compound that exhibits significant structural variety despite its metastable nature.
About Ca3SnS5
Ca3SnS5 is a complex ternary sulfide composed of calcium, tin, and sulfur. As a semiconducting material, it represents an interesting subject for structural analysis within the broader family of chalcogenide compounds.
While the material is characterized as being above the thermodynamic hull, its structural diversity is evidenced by numerous reported configurations across various databases. This suggests a complex energy landscape that continues to be a focus for researchers investigating metastable sulfide phases.
Key Properties
Cross-validated computational properties for Ca3SnS5, 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.
