About AlPS4
AlPS4 is a semiconducting compound composed of aluminum, phosphorus, and sulfur. As a thermodynamically stable material located on the convex hull, it represents a robust phase within its chemical system, making it a subject of significant interest for structural and electronic investigations. Its existence across multiple reported structures suggests a versatile architectural framework that warrants further exploration in solid-state chemistry. The material's electronic character positions it as a candidate for specialized applications where semiconducting properties are required. Its stability profile indicates that it maintains its integrity under standard conditions, providing a reliable platform for researchers to study the interplay between its constituent elements.
Key Properties
Cross-validated computational properties for AlPS4, 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.
