Abstract
A scalable, low-temperature solution process is used to synthesize precursor material for Pb-doped Bi<sub>0.7</sub> Sb<sub>1.3</sub> Te<sub>3</sub> thermoelectric nanocomposites. The controllable Pb-doping leads to the increase in the optical bandgap, thus delaying the onset of bipolar conduction. Furthermore, the solution synthesis enables nanostructuring, which greatly reduces thermal conductivity. As a result, this material exhibits a zT = 1 over the 513-613 K range.
