CrSn2
CrSn2 is a metallic intermetallic compound formed from chromium and tin that exhibits notable structural variety.
About CrSn2
CrSn2 is an intermetallic compound composed of chromium and tin. It exhibits a metallic electronic character, consistent with its elemental constituents, and is characterized by a significant degree of structural diversity as evidenced by numerous reported configurations across various databases. Due to its position relative to the thermodynamic hull, this material is considered metastable. Its study provides valuable insight into the complex phase space of chromium-tin systems and the factors governing the formation of transition metal stannides.
Key Properties
Cross-validated computational properties for CrSn2, aggregated across 6 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.
