The thermoelectric power factor of the narrow-gap semiconductor FeSb 2 is greatly enhanced in comparison to the isostructural homologues FeAs 2 and RuSb 2 . Comparative studies of magnetic and thermodynamic properties provide evidence that the narrow and correlated bands as well as the associated enhanced thermoelectricity are only specific to FeSb 2 . Our results point to the potential of FeSb 2 for practical thermoelectric application at cryogenic temperatures and stimulate the search for new correlated semiconductors along the same lines.
