Cu1Pd1Sr2
Cu1Pd1Sr2 is a semiconducting ternary alloy containing copper, palladium, and strontium that is studied for its structural diversity in catalytic research.
About Cu1Pd1Sr2
Cu1Pd1Sr2 is a semiconducting intermetallic compound belonging to the class of platinum-group alloy catalysts. Its unique electronic configuration and structural arrangement make it a subject of interest for researchers investigating specialized catalytic behaviors in complex metallic systems.
While this material exhibits a diverse range of reported structural variations, it is characterized as being thermodynamically above the hull. This suggests that the phase may be metastable under standard conditions, requiring specific synthesis pathways to stabilize its structure for potential experimental evaluation.
Key Properties
Cross-validated computational properties for Cu1Pd1Sr2, aggregated across 2 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.
