Hg1Mg2Sn1
Hg1Mg2Sn1 is a semiconducting ternary intermetallic compound composed of mercury, magnesium, and tin that is primarily studied for its structural complexity.
About Hg1Mg2Sn1
Hg1Mg2Sn1 is a complex ternary intermetallic compound composed of mercury, magnesium, and tin. It exhibits semiconducting electronic behavior, positioning it as a material of interest for specialized electronic research and solid-state physics investigations.
Despite its existence in multiple structural configurations across databases, this compound is characterized as being thermodynamically above the hull. This suggests that while it can be synthesized or modeled, it may face challenges regarding long-term phase stability under standard conditions.
Key Properties
Cross-validated computational properties for Hg1Mg2Sn1, 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.
