P2S3
P2S3 is a semiconducting binary sulfide of phosphorus that is considered a promising candidate for experimental synthesis.
About P2S3
P2S3 is a binary phosphorus sulfide compound that functions as a semiconductor. Its electronic properties make it an intriguing subject for research into non-oxide chalcogenide materials, particularly where specific electronic band structures are required for device integration.
As a near-hull material, P2S3 is considered likely to be synthesizable under appropriate experimental conditions. The existence of multiple reported structures across databases underscores its complexity and the ongoing interest in mapping its phase space for potential technological utility.
Key Properties
Cross-validated computational properties for P2S3, 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.
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 P2S3. Tight agreement means computed properties can be trusted without re-running calculations.
Agreement ScoreA normalized confidence score summarizing how closely independent DFT databases agree. Higher scores mean tighter cross-source agreement.
