PuSb
PuSb is a metallic plutonium antimonide compound that is considered stable enough for experimental synthesis and structural characterization.
About PuSb
PuSb is a metallic intermetallic compound composed of plutonium and antimony. Its electronic character is defined by its metallic nature, lacking a band gap, which influences its behavior in complex actinide systems. The compound is considered near-hull in terms of thermodynamic stability, suggesting it is a viable phase for synthesis and experimental study. With significant structural data available across multiple databases, it serves as a point of interest for researchers investigating the interplay between heavy actinides and pnictogens. Its properties are fundamental to understanding the broader physics of plutonium-based materials.
Key Properties
Cross-validated computational properties for PuSb, 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 PuSb. 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.
