An Effect of Fe2O3Additive on a Seebeck Coefficient and a Power Factor for SmCoO3Perovskite System

Year: 2010

Type: article

Abstract: SmCoO 3 system was investigated for their application to themoelectric materials.All specimens showed p-type semiconducting behavior and their electrical conductivity (σ), Seebeck coefficient (S) and power factor were measured at high temperature.And the effect of dopant ions on their thermoelectrical properties were also investigated.Fe 3+ ion doped into Co 3+ site enhanced the Seebeck coefficient and decreased the electrical conductivity simultaneously.The maximum Seebeck coefficient value for 60% doping case reached to 780 µV/K at 240 o C. However Fe 3+ doped system cause an negative effect on power factor value.In case of the pure phase, the maximum Seebeck coefficient value reached to 290 µV/K at 240 o C and the maximum electrical conductivity was obtained 748 1/ (ohm×cm) at 960 o C. As a result, the maximum power factor was obtained 1.49×10 -4 W/mK 2 at 550 o C.
