Au2InMg
Au2InMg is a semimetallic ternary intermetallic compound composed of gold, indium, and magnesium that exhibits metastable thermodynamic characteristics.
About Au2InMg
Au2InMg is a complex ternary intermetallic compound composed of gold, indium, and magnesium. It exhibits semimetallic electronic behavior, characterized by a near-zero band gap that suggests unique charge carrier dynamics within its crystalline lattice.
While multiple structural configurations have been documented for this composition across various databases, the material sits above the thermodynamic hull. This indicates that it is likely metastable under standard conditions, making it an intriguing subject for studies on phase stability and synthesis pathways.
Key Properties
Cross-validated computational properties for Au2InMg, 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.
