Au1Ga1Y2
Au1Ga1Y2 is a semiconducting ternary intermetallic compound that is thermodynamically metastable.
About Au1Ga1Y2
Au1Ga1Y2 is a complex ternary intermetallic compound composed of gold, gallium, and yttrium. It exhibits semiconducting electronic character, positioning it as an interesting subject for fundamental research into the electronic structure of rare-earth-containing alloys.
Due to its position above the thermodynamic hull, this material is considered likely unstable under standard conditions. Its existence in structural databases highlights the ongoing efforts to map the phase space of ternary systems involving precious metals and rare-earth elements.
Key Properties
Cross-validated computational properties for Au1Ga1Y2, 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.
