Palladium monosulfide is a stable, metallic compound composed of palladium and sulfur that is frequently studied for its structural and electronic properties.
About palladium monosulfide
Palladium monosulfide is a binary chalcogenide that exhibits metallic electronic character. As a thermodynamically stable compound residing on the convex hull, it represents a robust phase within the palladium-sulfur system, characterized by high structural reliability and extensive experimental documentation across multiple databases. Its metallic nature distinguishes it from many other metal sulfides that often function as semiconductors or insulators. This material is of significant interest in catalysis and materials science due to its stable coordination environment and the unique electronic properties afforded by the palladium-sulfur bonding network.
Key Properties
Cross-validated computational properties for palladium monosulfide, aggregated across 4 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.
