About NbPd2
NbPd2 is a metallic intermetallic compound belonging to the platinum-group alloy catalyst family. Its position on the convex hull indicates high thermodynamic stability, making it a robust candidate for materials science applications where structural integrity is paramount.
As a data-rich material with numerous reported structures, it serves as a critical subject for understanding the interplay between niobium and palladium. Its metallic nature facilitates efficient electron transport, which is essential for its potential performance in specialized catalytic environments.
Key Properties
Cross-validated computational properties for NbPd2, 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.
