Pd3S
Pd3S is a thermodynamically stable metallic compound composed of palladium and sulfur.
About Pd3S
Pd3S is a binary palladium sulfide that exhibits metallic electronic character. As a thermodynamically stable phase located on the convex hull, it represents a robust configuration within the palladium-sulfur system.
Its structural reliability is evidenced by its frequent appearance across multiple materials databases. This stability makes it a significant subject of study for understanding the interactions between transition metals and chalcogens in solid-state chemistry.
Key Properties
Cross-validated computational properties for Pd3S, aggregated across 5 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.
