Hg1Mg2Rh1
Hg1Mg2Rh1 is a semiconducting ternary alloy containing mercury, magnesium, and rhodium that is studied for its unique structural and electronic properties.
About Hg1Mg2Rh1
Hg1Mg2Rh1 is a complex ternary alloy featuring mercury, magnesium, and rhodium. As a member of the platinum-group alloy class, it exhibits semiconducting electronic behavior, which distinguishes it from the metallic nature typically associated with many noble metal systems.
While it has been documented across various structural configurations, its thermodynamic profile suggests it resides above the stability hull. This indicates that it is a metastable phase, making it a subject of interest for researchers studying the synthesis and stabilization of exotic intermetallic compounds.
Key Properties
Cross-validated computational properties for Hg1Mg2Rh1, 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.
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.
