About Au2Li1Mn1
Au2Li1Mn1 is a ternary intermetallic compound composed of gold, lithium, and manganese. As a semiconducting material, it represents a specialized area of study in solid-state chemistry where the interplay between noble metals and light alkali elements creates distinct electronic environments.
Despite its status as a thermodynamically metastable phase that sits above the convex hull, the compound has been documented across numerous structural configurations. This structural diversity makes it a subject of significant interest for researchers mapping the phase space of complex ternary alloys.
Key Properties
Cross-validated computational properties for Au2Li1Mn1, 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.
