Cd2Hg is a metallic intermetallic compound formed from cadmium and mercury that shows promising stability for experimental synthesis.
About Cd2Hg
Cd2Hg is a metallic intermetallic compound composed of cadmium and mercury. Its electronic structure is characterized by a lack of a band gap, identifying it as a conductor typical of metallic systems. The material exhibits near-hull thermodynamic stability, suggesting it is a viable candidate for synthesis and experimental investigation in laboratory settings.
With multiple reported structures across various databases, this compound represents a well-documented system within the cadmium-mercury binary phase space. Its existence as a stable phase makes it a subject of interest for researchers studying alloy formation and the fundamental physical interactions between these heavy group twelve elements.
Key Properties
Cross-validated computational properties for Cd2Hg, aggregated across 5 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.
