LuPt
LuPt is a thermodynamically stable metallic alloy consisting of lutetium and platinum that is frequently investigated for its diverse structural configurations.
About LuPt
LuPt is a metallic binary intermetallic compound composed of lutetium and platinum. As a member of the platinum-group alloy catalyst family, it exhibits significant structural diversity, with numerous reported phases across material databases. Its position on the convex hull confirms its thermodynamic stability, making it a robust candidate for fundamental studies in alloy behavior.
This material is valued for its metallic electronic character, which is characteristic of high-performance catalytic alloys. By combining a rare-earth element with a precious metal, LuPt serves as an important subject for understanding the synergistic effects that drive catalytic activity and structural stability in complex metallic systems.
Key Properties
Cross-validated computational properties for LuPt, aggregated across 4 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.
