Al2PdPt
Al2PdPt is a semiconducting ternary intermetallic alloy composed of aluminum, palladium, and platinum.
About Al2PdPt
Al2PdPt is a unique ternary intermetallic compound categorized within the platinum-group alloy catalysts. Characterized by its semiconducting electronic nature, this material represents an intriguing intersection of noble metal chemistry and aluminum-based alloying, offering a distinct electronic profile compared to traditional metallic catalysts.
While its thermodynamic stability indicates it lies above the hull, suggesting potential metastability, the compound remains a subject of interest in materials informatics. With multiple reported structures across databases, it serves as a valuable case study for understanding phase stability and structural diversity in complex ternary alloy systems.
Key Properties
Cross-validated computational properties for Al2PdPt, aggregated across 3 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.
