Sr2Sn
Sr2Sn is a thermodynamically stable semiconducting intermetallic compound composed of strontium and tin.
About Sr2Sn
Sr2Sn is a thermodynamically stable intermetallic compound that sits firmly on the convex hull, indicating significant structural robustness. As a semiconducting material, it represents a specialized electronic phase within the strontium-tin binary system, offering unique charge transport characteristics for fundamental materials science studies.
Given its status as a well-documented phase with numerous reported structures across multiple databases, this compound serves as a critical reference point for understanding the bonding and stability of alkaline-earth stannides. Its electronic nature makes it a subject of interest for researchers investigating the transition between metallic and semiconducting behaviors in binary alloys.
Key Properties
Cross-validated computational properties for Sr2Sn, 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.
