GaLaS3
GaLaS3 is a thermodynamically stable, semiconducting ternary sulfide compound composed of gallium, lanthanum, and sulfur.
About GaLaS3
GaLaS3 is a ternary sulfide compound characterized by its stable thermodynamic profile, placing it firmly on the convex hull of its constituent elements. As a semiconducting material, it represents a specialized inorganic structure that bridges the gap between simple binary sulfides and more complex multinary chalcogenides.
This material is of significant interest to researchers investigating the electronic and structural diversity of gallium-lanthanum-sulfur systems. Its stability suggests potential for integration into functional devices where reliable phase behavior is essential for long-term performance in semiconductor applications.
Key Properties
Cross-validated computational properties for GaLaS3, 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of GaLaS3. Tight agreement means computed properties can be trusted without re-running calculations.
