Sn2Tl2
Sn2Tl2 is a metallic tin-thallium compound that exists in a metastable state with diverse structural possibilities.
About Sn2Tl2
Sn2Tl2 is a metallic intermetallic compound composed of tin and thallium. Due to its electronic character, it exhibits conductive properties typical of metallic systems, though it is characterized by a lack of a band gap.
This material is noted for its structural diversity, with numerous reported configurations across multiple databases. However, it sits above the thermodynamic hull, suggesting it is a metastable or unstable phase that requires specific synthesis conditions to exist.
Key Properties
Cross-validated computational properties for Sn2Tl2, aggregated across 5 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.
