AgLiY2
AgLiY2 is a semiconducting ternary intermetallic compound containing silver, lithium, and yttrium that is currently categorized as a metastable phase.
About AgLiY2
AgLiY2 is a complex ternary compound composed of silver, lithium, and yttrium. As a semiconducting material, it represents a unique intersection of noble metal, alkali metal, and rare-earth chemistry, offering a distinct electronic profile that distinguishes it from simpler binary alloys. The compound is characterized by a notable structural diversity, with multiple reported configurations across materials databases. Because it resides above the thermodynamic hull, it is considered a metastable phase, which makes it a subject of interest for researchers studying synthetic pathways and the stabilization of complex intermetallics.
Key Properties
Cross-validated computational properties for AgLiY2, 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.
