Key Properties
Cross-validated computational properties for FeTeAs, aggregated across 3 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.

How It Compares
Within the skutterudite thermoelectrics class.
Within the broader class of skutterudite and related phosphide-based systems, FeTeAs distinguishes itself through its unique combination of iron, tellurium, and arsenic. While siblings like FeP2 and CoP2 are frequently studied for their specific electronic properties, FeTeAs offers a different structural landscape that may provide distinct advantages in thermal transport management compared to simpler binary phosphides like NiP or FeP.
