About LaMgZn2
LaMgZn2 is a metallic intermetallic compound composed of lanthanum, magnesium, and zinc. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement of these metallic elements.
The compound is characterized by its metallic electronic nature, lacking a band gap. Its presence across multiple structural databases underscores its significance as a well-defined material in the study of ternary alloy systems.
Key Properties
Cross-validated computational properties for LaMgZn2, 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.
