Au1Hg2Na1
Au1Hg2Na1 is a semiconducting ternary intermetallic compound that exhibits metastable thermodynamic behavior.

About Au1Hg2Na1
Au1Hg2Na1 is a complex ternary intermetallic compound composed of gold, mercury, and sodium. As a semiconducting material, it occupies a unique position in the electronic landscape, offering distinct charge transport behaviors that differ from typical metallic alloys.
Despite its existence in structural databases, this compound is characterized by its thermodynamic instability, placing it above the energy hull. This suggests that while it can be synthesized or observed under specific conditions, it remains a metastable phase of significant interest for fundamental materials research.
Key Properties
Cross-validated computational properties for Au1Hg2Na1, 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.
