Au2Cu1Ga1
Au2Cu1Ga1 is a semiconducting ternary intermetallic material composed of gold, copper, and gallium that often exists in metastable structural states.
About Au2Cu1Ga1
Au2Cu1Ga1 is a complex ternary intermetallic compound composed of gold, copper, and gallium. Its electronic character is defined as semiconducting, marking it as an interesting subject for studies into how transition metals and post-transition elements interact to influence charge transport properties.
While this material exhibits a diverse range of reported structural configurations, it is categorized as being above the thermodynamic hull. This suggests that it may exist as a metastable phase, requiring specific synthesis conditions to stabilize its crystalline arrangement for experimental investigation.
Key Properties
Cross-validated computational properties for Au2Cu1Ga1, 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.
