Ag2Au1Li1
Ag2Au1Li1 is a semiconducting ternary intermetallic compound composed of silver, gold, and lithium.
About Ag2Au1Li1
Ag2Au1Li1 is a complex ternary intermetallic compound composed of silver, gold, and lithium. As a semiconducting material, it occupies a unique position in the electronic landscape, bridging the gap between traditional metallic alloys and insulating compounds.
Due to its position relative to the thermodynamic ground state, this material is considered metastable. Its existence across multiple structural configurations suggests a rich phase space that remains a subject of interest for researchers investigating complex metallic systems.
Key Properties
Cross-validated computational properties for Ag2Au1Li1, 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
