Pseudo-nanostructure and trapped-hole release induce high thermoelectric performance in PbTe

Pseudo-nanostructure and trapped-hole release induce high thermoelectric performance in PbTe Thermoelectric materials can realize direct and mutual conversion between electricity and heat. However, developing a strategy to improve high thermoelectric performance is challenging because of strongly entangled electrical and thermal transport properties. We demonstrate a case in which both pseudo-nanostructures of vacancy clusters and dynamic charge-carrier regulation of trapped-hole release have b...
