About Pt1Y1Zn2
Pt1Y1Zn2 is a complex ternary intermetallic compound classified within the platinum-group alloy catalysts. Characterized by a semiconducting electronic structure, this material represents a unique intersection of noble metal chemistry and rare-earth integration.
Due to its position above the thermodynamic hull, it is considered a metastable phase. Research into this compound contributes to the broader understanding of how specific atomic arrangements in platinum-based alloys influence catalytic activity and electronic behavior in advanced materials design.
Key Properties
Cross-validated computational properties for Pt1Y1Zn2, 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.
