Abstract

The thermoelectric properties of materials with compositions NaPb _18-xSn_xMTe₂₀ (M=Sb, Bi, x=0, 3, 5, 9, 13, 16 and 18) were investigated in the temperature range 300-670K. All compositions exhibited p-type behavior over the measured temperature range. Electronic properties and transport were tuned through the manipulation of the Pb/Sn ratio. Increasing the Sn fraction results in an increase in electrical conductivity and a decrease in thermopower. The compositions NaPb₁₃Sn ₅SbTe₂₀ and NaPb₉Sn₉SbTe ₂₀ show a lattice thermal conductivity of ̃1 W/m/K at room temperature.
