About NiSn
NiSn is a metallic intermetallic compound composed of nickel and tin. Its electronic character confirms it as a conductor, making it a subject of interest for fundamental studies in transition metal-main group alloy systems. The material is characterized by a significant number of reported structural variations across various databases, highlighting its complex phase behavior. It is considered near-hull in terms of thermodynamic stability, suggesting it is a viable candidate for experimental synthesis under controlled conditions. This accessibility makes it a valuable model system for researchers investigating the interplay between nickel and tin at the atomic scale.
Key Properties
Cross-validated computational properties for NiSn, 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
