HoPd3
HoPd3 is a thermodynamically stable intermetallic compound formed from holmium and palladium that exhibits metallic electronic properties.
About HoPd3
HoPd3 is a robust intermetallic compound composed of holmium and palladium. As a member of the platinum-group alloy family, it exhibits metallic conductivity, reflecting the strong hybridization between the rare-earth element and the transition metal. Its position on the convex hull confirms it is a thermodynamically stable phase, making it a reliable subject for structural and electronic investigation.
This material is of significant interest in materials science due to its well-defined structural characteristics, supported by extensive data across multiple crystallographic databases. Its metallic nature and stable composition make it a valuable candidate for fundamental research into the catalytic behavior of rare-earth transition metal alloys.
Key Properties
Cross-validated computational properties for HoPd3, 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.
