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 …

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 …

PbSe is an inexpensive alternative for PbTe as a mid-temperature thermoelectric material,
but few investigations have been reported about its intrinsic properties despite recent efforts …

Te-free PbS has been regarded as a promising alternative candidate for PbTe
thermoelectric materials due to its advances of low-cost, earth-abundant. In this work, we …

PbSe was expected to have a smaller bandgap and higher thermalconductivity than PbTe.
Instead, these values are about the same at high temperature leading to comparable …

Traditional thermoelectric (TE) materials usually contain scarce and expensive chemical
elements, weakening the commercial value in clean energy community. With further …

It was recently predicted [D. Parker DJ Singh, Phys. Rev. B 82, 035204 (2010)], contrary to
then-prevalent opinion, that p-type PbSe would be a good thermoelectric material. This …

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 …

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

Ideal thermoelectrics shall possess a high average ZT, which relies on high carrier mobility
and appropriate carrier density at operating temperature. However, conventional doping …
