Abstract

Thermoelectric materials Ag _0.8Pb ₁₈SbTe ₂₀ alloyed with Se in the composition of Ag _0.8Pb ₁₈SbTe _20-x Se _x (x = 0, 5, 10, 15) were prepared by a high-pressure method. The composition dependence of transport properties was studied from 100 K to room temperature. The thermal conductivity of Ag _0.8Pb ₁₈SbTe ₂₀ was depressed sharply by alloying with Se, and the Seebeck coefficient and resistivity were tuned effectively by adjusting the Se content. The maximum figure of merit ZT = 0.43 was obtained at x = 10, which is about 70% higher than that of the unalloyed sample.
