Li2MgSn
Li2MgSn is a thermodynamically stable semimetallic ternary compound composed of lithium, magnesium, and tin.
About Li2MgSn
Li2MgSn is a ternary intermetallic compound that occupies a position of thermodynamic stability on the convex hull. Its electronic character is defined by a near-zero-gap semimetallic state, making it a subject of interest for researchers investigating the fundamental behavior of complex ternary alloys.
Due to its structural consistency across multiple databases, this material serves as a reliable reference point for computational studies. Its specific arrangement of lithium, magnesium, and tin atoms provides a stable platform for exploring electronic properties in the absence of a significant band gap.
Key Properties
Cross-validated computational properties for Li2MgSn, 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.
