Abstract
The effects of Rh doping on the thermoelectric properties of Pt 1-xRhxAs2 (x = 0, 0.005, and 0.01) with pyrite structure were studied by conducting measurements of electrical resistivity ρ, Seebeck coefficient S, and thermal conductivity κ. The sample with x = 0.005 exhibited large S and low ρ, resulting in a maximum power factor (S 2 / ρ) of 65 μW/cmK2 at 440 K. The peculiarly shaped "corrugated flat band" predicted for PtSb2 might explain the enhanced thermoelectric properties of doped PtAs2.
