BaPS3
BaPS3 is a thermodynamically stable, wide-gap insulating compound consisting of barium, phosphorus, and sulfur.
About BaPS3
BaPS3 is a ternary sulfide compound composed of barium, phosphorus, and sulfur. As a thermodynamically stable phase residing on the convex hull, it represents a robust crystalline arrangement within its chemical system. Its electronic character is defined by a wide band gap, classifying it as an insulator with potential interest for specialized dielectric or optical applications. The compound is characterized by a well-defined structural profile, reflecting the stability inherent to its atomic configuration. Its existence as a stable phase makes it a significant subject for researchers investigating the fundamental properties of barium-based chalcogenides.
Key Properties
Cross-validated computational properties for BaPS3, 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.
