Hg2YZn
Hg2YZn is a semiconducting ternary intermetallic compound that exhibits metastable thermodynamic behavior.
About Hg2YZn
Hg2YZn is a complex ternary intermetallic compound characterized by its semiconducting electronic nature. Its composition, involving mercury, yttrium, and zinc, places it in a specialized category of materials that are subject to ongoing structural investigation across multiple databases. The compound is noted for being thermodynamically metastable, as it resides above the convex hull. This status suggests that while it can be synthesized or observed in specific experimental conditions, it remains a subject of interest for researchers studying the stability limits of mercury-based ternary alloys.
Key Properties
Cross-validated computational properties for Hg2YZn, aggregated across 3 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.
