Fig. 3From: Thermoelectric composite with enhanced figure of merit via interfacial dopingThermal conductivity and ZT of a composite made of Pb-coated glass beads in a (Bi0.25Sb0.75)2Te3 host matrix. The temperature dependence of κ and ZT are shown. ZT clearly is enhanced in the 5% composite over the values of the bulk hostBack to article page
