Au1Pd2Sc1
Au1Pd2Sc1 is a semiconducting ternary alloy containing gold, palladium, and scandium that is studied for its unique electronic properties within the platinum-group catalyst family.
About Au1Pd2Sc1
Au1Pd2Sc1 is a ternary intermetallic compound categorized within the platinum-group alloy catalysts. It exhibits semiconducting electronic behavior, which distinguishes it from the metallic nature typically associated with many noble metal alloys.
Due to its position above the thermodynamic hull, this material is considered metastable. Its existence within a significant body of reported structures highlights its interest to researchers investigating complex phase spaces in catalytic material design.
Key Properties
Cross-validated computational properties for Au1Pd2Sc1, 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.
