SmZn
SmZn is a stable metallic compound formed from samarium and zinc that is frequently studied for its structural properties.
About SmZn
SmZn is a binary intermetallic compound composed of samarium and zinc. As a thermodynamically stable phase located on the convex hull, it represents a robust configuration of these elements that remains consistent across various structural studies. Its metallic electronic character indicates a lack of a band gap, identifying it as a conductor typical of metal-rich intermetallic systems. This stability makes it a significant subject for researchers investigating rare-earth zinc alloys. Given the presence of multiple reported structures across databases, SmZn serves as a foundational reference point for understanding phase formation and bonding in samarium-based binary systems.
Key Properties
Cross-validated computational properties for SmZn, 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.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of SmZn. 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.
