Abstract

(Graph Presented) Co-nanostructuring of PbTe with two kinds of metallic nanoparticles (Pb and Sb) can significantly increase its power factor at high temperatures (up to 87% at 700 K; see picture, ZT = figure of merit). The electrical conductivity is dramatically increased at high temperatures without degrading the thermopower. This emergent synergy results only when both Pb and Sb nanocrystals are present.
