The thermoelectric properties of the Zintl compound YbZn2Sb2 with isoelectronic substitution of Zn by Mn in the anionic (Zn2Sb2)2− framework have been studied. The p-type YbZn2−xMnxSb2 (0.0 ≤ x ≤ 0.4) samples were prepared via melting followed by annealing and hot-pressing. Thermoelectric property measurement showed that the Mn substitution effectively lowered the thermal conductivity for all the samples, while it significantly increased the Seebeck coefficient for x < 0.2. As a result, a… CONTINUE READING
