High carrier mobility is critical to improving thermoelectric performance over a broad temperature range. However, traditional doping inevitably deteriorates mobility. Herein, we develop strategy for fine tuning of defects improve To begin, n-type PbTe created by compensating the intrinsic Pb vacancy in bare PbTe. Excess Pb2+ reduces scattering, resulting high ∼3400 cm2 V-1 s-1. Then, excess Ag introduced compensate remaining vacancies. We find that exhibits dynamic process with increasing...

Abstract The scarcity of Te hampers the widespread use Bi 2 3 ‐based thermoelectric modules. Here, module potential PbSe is investigated by improving its carrier mobility. Initially, large crystals are grown with temperature gradient method to mitigate grain boundary effects on transport. Subsequently, light doping <1mole‰ halogens (Cl/Br/I) increases room‐temperature mobility ~1600 cm V −1 s , achieved reducing concentration compared traditional heavy doping. Crystal growth design and...
Abstract Ideal thermoelectrics shall possess a high average ZT , which relies on carrier mobility and appropriate density at operating temperature. However, conventional doping usually results in temperature‐independent concentration, making performance optimization over wide temperature range be challenging. This work demonstrates the combination of lattice plainification dynamic strategies is an effective route to boost N‐type PbSe. Because Sn Pb have similar ionic radii electronegativity,...
