Mg6SiSn2
Mg6SiSn2 is a semimetallic magnesium-based intermetallic compound that is theoretically stable and potentially synthesizable.
About Mg6SiSn2
Mg6SiSn2 is a complex intermetallic compound composed of magnesium, silicon, and tin. Its electronic structure is characterized as a near-zero-gap semimetal, placing it in a unique position between traditional semiconductors and metallic conductors.
This material is considered to be near the thermodynamic hull, suggesting that it is likely synthesizable under appropriate experimental conditions. With multiple reported structures across major databases, it remains a subject of interest for researchers investigating multi-element magnesium-based systems.
Key Properties
Cross-validated computational properties for Mg6SiSn2, 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.
