Abstract

The thermoelectric properties of materials with compositions NaPb 18-xSnxMTe20 (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.
