FeSb2
FeSb2 is a thermodynamically stable, metallic iron-antimony compound often studied within the context of skutterudite-related thermoelectric materials.
About FeSb2
FeSb2 is a thermodynamically stable intermetallic compound that crystallizes in a structure closely related to the skutterudite family. As a metallic phase, it exhibits distinct electronic properties that differentiate it from the more insulating or semiconducting members of its structural class, making it a subject of significant interest in condensed matter physics.
Its structural integrity and presence on the convex hull suggest high stability, which is a critical factor for materials intended for long-term functional applications. Researchers study this compound to understand the interplay between its electronic configuration and its potential for energy conversion, particularly in the context of thermoelectric material design.
Key Properties
Cross-validated computational properties for FeSb2, aggregated across 5 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.

How It Compares
Within the skutterudite thermoelectrics class.
Within the broader family of pnictides and related skutterudite-type phases, FeSb2 stands out due to its metallic nature compared to the more commonly semiconducting phosphides like FeP2 or CoP2. While many of its siblings are investigated primarily for their optimized carrier transport, FeSb2 provides a unique metallic baseline that helps researchers map the transition of physical properties across the iron-group pnictide series.
