LiMgIn2
LiMgIn2 is a semimetallic ternary intermetallic compound that is considered a likely candidate for laboratory synthesis.
About LiMgIn2
LiMgIn2 is a ternary intermetallic compound composed of lithium, magnesium, and indium. It exhibits a near-zero-gap electronic structure, placing it in the category of semimetallic materials that often display unique transport properties due to their limited density of states at the Fermi level.
This material is recognized for its potential synthesizability, as it sits very close to the thermodynamic stability hull. With multiple reported crystal structures across various databases, it represents an interesting subject for researchers investigating complex metallic phases and their structural evolution.
Key Properties
Cross-validated computational properties for LiMgIn2, 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.
