From a structural and economic perspective, tellurium-free PbSe can be an attractive
alternative to its more expensive isostructural analogue of PbTe for intermediate …

We show an example of hierarchically designing electronic bands of PbSe toward excellent
thermoelectric performance. We find that alloying 15 mol% PbTe into PbSe causes a …

This short review discusses recent advances in n-type PbSe-based bulk thermoelectric
materials. Their performance has rapidly progressed recently and emerges as one of most …

Thermoelectric materials with high average power factor and thermoelectric figure of merit
(ZT) has been a sought-after goal. Here, we report new n-type thermoelectric system Cu x …

In this work, the thermoelectric performance of p-type PbSe was improved dramatically by
enhancing the Seebeck coefficient and reducing electronic thermal conductivity through …

A high average ZT value (ZTave) of∼ 1.13 in an n-type PbSe-based thermoelectric material
at 300–873 K has been achieved in this work. Its high thermoelectric performance originates …

In this study, we prepared a series of Ag-doped PbSe bulk materials by a melting–
quenching process combined with a subsequent spark plasma sintering process, and …

Introducing structural defects such as vacancies, nanoprecipitates, and dislocations is a
proven means of reducing lattice thermal conductivity. However, these defects tend to be …

PbSe-based thermoelectric materials exhibit promising ZT values at medium temperature,
but its near-room-temperature thermoelectric properties are overlooked, thus restricting its …

Historically PbSe has underperformed PbTe in thermoelectric efficiency and has been
regarded as an inferior relative to its telluride congener. However, the fifty-fold greater …
