ScSn
ScSn is a metallic intermetallic compound formed from scandium and tin that displays a wide variety of structural configurations.
About ScSn
ScSn is a metallic intermetallic compound composed of scandium and tin. As a metallic system, it exhibits characteristic electronic behavior typical of transition metal-post-transition metal alloys, reflecting the interaction between the d-orbitals of scandium and the p-orbitals of tin. The compound is noted for its structural complexity, supported by a significant volume of reported structural data across multiple databases. While it exists in various configurations, its position relative to the thermodynamic hull suggests it is a metastable phase that requires specific synthesis conditions to stabilize.
Key Properties
Cross-validated computational properties for ScSn, aggregated across 4 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.
