CuPd
CuPd is a thermodynamically stable metallic alloy consisting of copper and palladium that is primarily used in catalytic research.
About CuPd
CuPd is a metallic alloy composed of copper and palladium that sits firmly on the thermodynamic convex hull. Its stable crystalline architecture makes it a subject of significant interest for researchers investigating the synergy between base metals and precious platinum-group elements.
As a member of the platinum-group alloy catalyst class, this material is utilized in advanced chemical processing where structural integrity and metallic conductivity are essential. Its high data richness across multiple databases reflects its importance as a benchmark material for understanding alloy phase stability.
Key Properties
Cross-validated computational properties for CuPd, aggregated across 5 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 CuPd. 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.
Sources ComparedNumber and names of computational sources with comparable entries for this formula.
Space Group ConsensusWhether independent sources predict the same crystal symmetry for the lowest-energy structure.
