YZr
YZr is a metallic binary compound consisting of yttrium and zirconium that exhibits metastable characteristics.
About YZr
YZr is a metallic binary compound formed from yttrium and zirconium. As a metallic system, it exhibits characteristic electronic behavior associated with its elemental constituents, lacking a band gap. Its structural complexity is evidenced by a high number of reported configurations across multiple databases. Due to its position relative to the thermodynamic hull, YZr is considered a metastable phase. This suggests that while it can be observed in various structural forms, it may require specific synthesis conditions to stabilize compared to more conventional equilibrium phases.
Key Properties
Cross-validated computational properties for YZr, 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.
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.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of YZr. Tight agreement means computed properties can be trusted without re-running calculations.
