HgOs
HgOs is a metallic binary compound of mercury and osmium that displays significant structural complexity despite its thermodynamic instability.
About HgOs
HgOs is a metallic binary compound composed of mercury and osmium. It represents a unique intersection of a heavy post-transition metal and a dense platinum-group metal, characterized by a lack of a band gap which confirms its conductive electronic nature.
Despite its thermodynamic position above the hull, suggesting inherent instability, the compound exhibits significant structural diversity. The existence of numerous reported structures across multiple databases highlights its complex phase landscape and interest within fundamental materials research.
Key Properties
Cross-validated computational properties for HgOs, aggregated across 4 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.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
