About Au2Cu1Sc1
Au2Cu1Sc1 is a complex ternary intermetallic compound composed of gold, copper, and scandium. Its electronic structure exhibits semimetallic behavior, characterized by a near-zero band gap that influences its charge transport properties.
This material is primarily of interest in fundamental condensed matter research due to its structural diversity. As a compound that sits above the thermodynamic hull, it represents a metastable phase that provides insights into the synthesis and stability of multi-element metallic systems.
Key Properties
Cross-validated computational properties for Au2Cu1Sc1, 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.
