InLaLi2
InLaLi2 is a stable, semiconducting ternary intermetallic compound formed from indium, lanthanum, and lithium.
About InLaLi2
InLaLi2 is a distinct ternary intermetallic compound composed of indium, lanthanum, and lithium. As a thermodynamically stable phase located on the convex hull, it represents a robust structural configuration within its chemical system.
This material exhibits semiconducting electronic character, making it a subject of interest for researchers investigating the interplay between rare-earth elements and post-transition metals. With multiple reported structures across databases, it serves as a valuable reference point for understanding complex ternary phase stability.
Key Properties
Cross-validated computational properties for InLaLi2, aggregated across 3 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.
