S2ScTl is a stable semiconducting ternary sulfide compound with a diverse range of known structural configurations.
About S2ScTl
S2ScTl is a ternary sulfide compound that exhibits semiconducting electronic properties. As a thermodynamically stable phase located on the convex hull, it represents a robust configuration of scandium, thallium, and sulfur atoms that maintains structural integrity under standard conditions. The material is characterized by a diverse structural landscape, with multiple reported configurations across crystallographic databases. This structural variety highlights its potential interest for researchers investigating complex chalcogenide systems for specialized electronic or optoelectronic functions.
Key Properties
Cross-validated computational properties for S2ScTl, 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.
