Non-equilibrium processing leads to record high thermoelectric figure of merit in PbTe–SrTe
Abstract
Alloying lead telluride has proven a good strategy to improve its thermoelectric properties. Here, the authors use a rapid temperature quenching to prepare compounds alloyed above the thermodynamic solubility limit, which results in band convergence and high thermoelectric figures of merit.
