Phosphorus is a versatile, thermodynamically stable elemental material that acts as a wide-gap insulator with diverse structural forms.
About Phosphorus
Phosphorus is a fundamental elemental material that exhibits a wide-band-gap insulating electronic character. As a thermodynamically stable substance located on the convex hull, it serves as a critical building block in chemical and materials science research. Its structural diversity is evidenced by its presence in numerous reported crystalline forms across major databases. This versatility allows it to be adapted for a wide range of technological and industrial purposes, from agricultural fertilizers to specialized electronic components. Its stability and unique bonding characteristics make it a subject of intense study for both fundamental physics and practical engineering applications.
Key Properties
Cross-validated computational properties for Phosphorus, aggregated across 6 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 P. 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.
Hull SpreadDifference between the highest and lowest energy-above-hull values reported by comparable sources. Smaller spread means less thermodynamic disagreement.
