Hg1Pb1Y2
Hg1Pb1Y2 is a semiconducting ternary compound consisting of mercury, lead, and yttrium that is currently considered thermodynamically unstable.
About Hg1Pb1Y2
Hg1Pb1Y2 is a complex ternary compound composed of mercury, lead, and yttrium. As a semiconducting material, it exhibits electronic properties that differentiate it from simple metallic alloys, positioning it as a subject of interest for fundamental solid-state research.
While the compound has been identified across multiple structural configurations, it is characterized by a thermodynamic state that sits above the hull. This suggests that the material may be metastable or difficult to synthesize in a pure, bulk form under standard conditions.
Key Properties
Cross-validated computational properties for Hg1Pb1Y2, 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.
