摘要：

The thermoelectric properties of InxPb1-3x/200Te (with x = 0.005, 0.01, 0.015, 0.02) were investigated in the temperature range from 300 K to 700 K. The materials were found to be n-type semiconductors. The values of the Seebeck coefficient increase with increasing In content. The low thermal conductivity values < 1.9 Wm(-1)K(-1) make these materials potential candidates for thermoelectric applications. The most promising sample in the current study, with x = 0.005, possesses a figure-of-merit of ZT = 0.45 at 600 K as determined on pellets directly cut from the ingot.
