Hf2Hg1Re1
Hf2Hg1Re1 is a complex, semimetallic ternary intermetallic compound containing hafnium, mercury, and rhenium.
About Hf2Hg1Re1
Hf2Hg1Re1 is a ternary intermetallic compound composed of hafnium, mercury, and rhenium. It exhibits a near-zero-gap electronic structure, placing it in the category of semimetallic materials which often display interesting transport phenomena due to the proximity of the valence and conduction bands.
As a material that sits above the thermodynamic hull, Hf2Hg1Re1 is considered metastable under standard conditions. Its existence in multiple reported structures suggests a complex energy landscape, making it a subject of interest for researchers studying phase stability and structural diversity in heavy-element intermetallics.
Key Properties
Cross-validated computational properties for Hf2Hg1Re1, 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.
