Au1Ga1Mg2 is a semimetallic ternary intermetallic compound composed of gold, gallium, and magnesium.
About Au1Ga1Mg2
Au1Ga1Mg2 is a ternary intermetallic compound composed of gold, gallium, and magnesium. Its electronic character is defined as near-zero-gap, placing it in the category of semimetallic materials that often exhibit unique transport properties due to the proximity of their valence and conduction bands.
While this material has been identified across multiple structural configurations in computational databases, its thermodynamic status above the hull suggests it is likely unstable under standard conditions. Its study is primarily focused on understanding the complex phase space of gold-gallium-magnesium alloys.
Key Properties
Cross-validated computational properties for Au1Ga1Mg2, 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.
