AsAuLi2
AsAuLi2 is a semiconducting ternary compound consisting of arsenic, gold, and lithium that is currently studied for its unique structural and thermodynamic characteristics.
About AsAuLi2
AsAuLi2 is a ternary inorganic compound composed of arsenic, gold, and lithium. It exhibits semiconducting electronic behavior, positioning it as an interesting subject for fundamental research into the interplay between heavy metallic elements and light alkali metals within a crystalline lattice.
While the compound has been identified across multiple structural databases, it is characterized by a thermodynamic state that sits above the hull. This suggests that the material may be metastable or difficult to synthesize under standard conditions, making it a focus for studies on phase stability and synthesis pathways.
Key Properties
Cross-validated computational properties for AsAuLi2, 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.
