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

As an inexpensive and earth abundant analogue of PbTe, PbSe has aroused growing
attention recently as advanced thermoelectric materials. In the present report, the effect of …

Among the intricately coupled thermoelectric parameters, carrier effective mass (m*) and
carrier density (n) are two key parameters to determine the electrical transport properties. To …

Here, we have systematically explored the effects of rare-earth metal La doping on the
thermoelectric properties of PbSe. The results show that i) La is an effective n-type dopant to …

To date, thermoelectric performance has been enhanced through improving the power factor
and/or reducing the lattice thermal conductivity. Here, we report an effective method of …

Chemical doping is an indispensable means of improving the performance of thermoelectric
materials, while one bottleneck for maximizing optimization is the low solubility of dopants …

PbSe is an alternative of the well-known moderate-temperature thermoelectric material
PbTe, and has attracted much attention because of its advantages of high earth-abundance …

PbSe has been expected to be a competitor of the excellent thermoelectric material PbTe,
whereas its performance has proved to be limited by its intrinsic electronic structure. In this …

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

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 …
