LiAl2Au
LiAl2Au is a metastable, semimetallic ternary compound consisting of lithium, aluminum, and gold.
About LiAl2Au
LiAl2Au is a complex ternary intermetallic compound composed of lithium, aluminum, and gold. It exhibits a near-zero-gap electronic character, placing it in the category of semimetallic materials that bridge the gap between conductive metals and insulating semiconductors.
As a metastable phase, this compound represents a specific structural configuration that requires precise synthesis conditions to stabilize. Its existence within multiple structural databases highlights its role as a subject of interest for researchers investigating the interplay of light and heavy elements in electronic materials.
Key Properties
Cross-validated computational properties for LiAl2Au, 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.
