DyZn
DyZn is a stable metallic compound formed from dysprosium and zinc that is frequently studied for its structural properties.
About DyZn
DyZn is a metallic intermetallic compound composed of dysprosium and zinc. As a thermodynamically stable phase located on the convex hull, it represents a robust structural configuration that persists under standard conditions.
Its metallic nature and structural reliability make it a subject of interest in materials science, particularly for studies involving rare-earth transition metal alloys. The compound is well-documented across multiple databases, reflecting its significance in fundamental research.
Key Properties
Cross-validated computational properties for DyZn, 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 DyZn. Tight agreement means computed properties can be trusted without re-running calculations.
Agreement ScoreA normalized confidence score summarizing how closely independent DFT databases agree. Higher scores mean tighter cross-source agreement.
Hull SpreadDifference between the highest and lowest energy-above-hull values reported by comparable sources. Smaller spread means less thermodynamic disagreement.
Sources ComparedNumber and names of computational sources with comparable entries for this formula.
Space Group ConsensusWhether independent sources predict the same crystal symmetry for the lowest-energy structure.
