CdSn
CdSn is a metallic intermetallic compound formed from cadmium and tin that exhibits structural complexity and metastable thermodynamic characteristics.
About CdSn
CdSn is a binary intermetallic compound composed of cadmium and tin. As a metallic system, it exhibits characteristic electronic behavior associated with its elemental constituents, reflecting a complex interplay between the d-block and p-block metals. While it demonstrates significant structural diversity with numerous reported configurations across various databases, it is classified as thermodynamically unstable relative to the ground-state hull. This suggests that while it can be synthesized in specific experimental conditions, it exists in a metastable state.
Key Properties
Cross-validated computational properties for CdSn, 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of CdSn. Tight agreement means computed properties can be trusted without re-running calculations.

How It Compares
As a binary intermetallic system, CdSn represents a unique combination of heavy metals that does not fit neatly into common stoichiometric semiconductor families. Its metallic nature and tendency to exist above the thermodynamic hull distinguish it from more stable, naturally occurring mineral phases, marking it as a subject of interest for fundamental studies in phase formation and metastable alloy synthesis.
