Thermoelectric properties of hole doped FeSb/sub 2/

Abstract

FeSb/sub 2/ is a diamagnetic semiconductor where the Fe 3d levels are located just below the band gap. A series of systematically Sn substituted FeSb/sub 2-x/Sn/sub x/ samples with x = 0-0.15 has been synthesized and we explore the thermoelectric properties of these samples as the Fermi level is shifted down into the region of the Fe 3d levels.
