BePd
BePd is a thermodynamically stable metallic alloy of beryllium and palladium used in materials science research.
About BePd
BePd is a metallic intermetallic compound composed of beryllium and palladium. As a member of the platinum-group alloy family, it is recognized for its thermodynamic stability, sitting securely on the convex hull, which suggests a robust structural configuration under standard conditions.
This material is characterized by its metallic electronic nature, lacking a band gap. With a significant number of reported structures across multiple databases, it stands as a well-documented subject of interest for researchers investigating the fundamental properties of transition metal alloys and their potential catalytic utility.
Key Properties
Cross-validated computational properties for BePd, 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 BePd. 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.

How It Compares
Within the platinum-group alloy catalysts class.
Within the diverse group of platinum-group alloys, BePd distinguishes itself through its specific stoichiometry compared to more complex systems like IrSe2 or As2Pt. While compounds such as BaPd share the palladium-based framework, BePd represents a simpler, highly stable binary arrangement that serves as a baseline for understanding how lighter elements like beryllium influence the electronic and structural behavior of noble metal alloys.
