Abstract

Abstract : A scalable, low‐temperature solution process is adopted to synthesize the precursor material of Pb‐doped Bi0.7 Sb1.3 Te3 thermoelectric nanocomposites, described in article number 1605140 by Je‐Hyeong Bahk, Gerald Jeffrey Snyder, Yue Wu, and co‐workers. The controllable Pb‐doping leads to the increase in the optical bandgap, thus delaying the onset of bipolar conduction. Furthermore, the solution synthesis tailors the nanostructuring, which greatly diminishes the thermal conductivity. Overall, this material exhibits a zT > 1 over the 513–613 K range.
