About Ga1Li2Y1
Ga1Li2Y1 is a complex ternary compound composed of gallium, lithium, and yttrium. As a semimetallic material with a near-zero electronic gap, it exhibits unique conductive properties that distinguish it from standard insulating or semiconducting alloys. Its electronic character suggests potential for specialized applications in condensed matter physics where precise control over charge carrier density is required. The material is characterized by a high degree of structural diversity, as evidenced by numerous reported configurations in computational databases. Because it sits above the thermodynamic hull, it is considered a metastable phase, which often indicates that its synthesis requires specific kinetic control or high-pressure conditions to stabilize its lattice.
Key Properties
Cross-validated computational properties for Ga1Li2Y1, aggregated across 2 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.
