InLiY2
InLiY2 is a metastable, semimetallic ternary compound containing indium, lithium, and yttrium.
About InLiY2
InLiY2 is a complex ternary compound composed of indium, lithium, and yttrium. Its electronic structure is characterized as near-zero-gap, placing it in the category of semimetallic materials that often exhibit unique transport properties.
Due to its position above the thermodynamic hull, this compound is considered metastable. While it has been identified across multiple structural databases, its relative instability suggests it may require specific synthesis conditions to stabilize its crystalline lattice.
Key Properties
Cross-validated computational properties for InLiY2, 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.
