Au2LiSi
Au2LiSi is a semiconducting ternary compound composed of gold, lithium, and silicon that is currently being investigated for its metastable structural properties.
About Au2LiSi
Au2LiSi is a ternary compound that integrates gold, lithium, and silicon into a semiconducting framework. Its electronic character suggests potential for specialized optoelectronic or sensor applications, though its current status as a metastable phase makes it a subject of fundamental materials research.
Because it exists above the thermodynamic hull, Au2LiSi represents a challenging synthetic target. Understanding its structural evolution across multiple databases provides insights into the complex bonding interactions between noble metals, alkali metals, and semiconductors.
Key Properties
Cross-validated computational properties for Au2LiSi, 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.
