Hg2Na1Sb1
Hg2Na1Sb1 is a semiconducting ternary compound characterized by its structural diversity and thermodynamic instability.
About Hg2Na1Sb1
Hg2Na1Sb1 is a complex ternary compound composed of mercury, sodium, and antimony. As a semiconducting material, it exhibits electronic properties that distinguish it from simple metallic alloys, positioning it as a subject of interest for fundamental solid-state research.
Despite its status as a thermodynamically unstable phase located above the hull, this material has been documented across numerous structural configurations. This structural diversity suggests a complex energy landscape that continues to challenge current understanding of mercury-based intermetallic systems.
Key Properties
Cross-validated computational properties for Hg2Na1Sb1, 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.
