Hg2K1Na1
Hg2K1Na1 is a semimetallic ternary amalgam of mercury, potassium, and sodium used primarily in fundamental materials science research.
About Hg2K1Na1
Hg2K1Na1 is a ternary intermetallic compound composed of mercury, potassium, and sodium. As a near-zero-gap material, it exhibits semimetallic electronic characteristics that distinguish it from traditional insulating or semiconducting alloys. Its structural complexity is evidenced by the wide range of reported configurations within experimental databases. Being positioned above the thermodynamic hull, this compound is considered metastable, requiring specific conditions for synthesis and preservation. Its role is primarily centered on fundamental materials research into the bonding behaviors of alkali metal amalgams.
Key Properties
Cross-validated computational properties for Hg2K1Na1, 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.
