CuSn
CuSn is a metallic binary intermetallic compound that is theoretically stable and exhibits a wide variety of structural arrangements.
About CuSn
CuSn is a metallic intermetallic compound formed from copper and tin. It is characterized by its lack of a band gap, reflecting its conductive nature, and is considered a near-hull phase, suggesting it is a viable candidate for experimental synthesis and characterization.
With a high degree of structural complexity, this material is represented by numerous reported crystal structures across multiple databases. Its stability profile makes it a subject of interest for researchers investigating binary alloys and phase formation in metallic systems.
Key Properties
Cross-validated computational properties for CuSn, 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
