Au1Hg2Y1
Au1Hg2Y1 is a semiconducting intermetallic compound containing gold, mercury, and yttrium that exhibits significant structural variety despite its metastable nature.
About Au1Hg2Y1
Au1Hg2Y1 is a complex intermetallic compound composed of gold, mercury, and yttrium. As a semiconducting material, it represents a specialized niche in solid-state chemistry where the interplay of heavy elements and rare-earth components dictates its electronic behavior.
Despite its structural diversity, the compound is characterized as being above the thermodynamic hull. This suggests that while it can be synthesized and observed in various structural configurations, it remains a metastable phase that requires specific conditions to persist.
Key Properties
Cross-validated computational properties for Au1Hg2Y1, 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.
