Abstract Al doped PbTe-PbSe alloys were successfully prepared with high pressure
synthesis followed by spark plasma sintering. The incorporation of Se shows a dual effect on …

The n-type PbTe still maintains relatively low thermoelectric performance compared with its
p-type counterpart. Thus, to promote its performance in n-type PbTe, we conduct successive …

PbTe-based semiconductor thermoelectric materials are currently active areas of research.
In this work, Na-and Ba-doped PbTe 0.5 Se 0.5 alloys were prepared by vacuum melting …

PbTe is a promising thermoelectric material, but the properties in n-type PbTe need further
improvement to match its advanced p-type material. In this work, the thermoelectric …

Much progress on highly efficient thermoelectric materials have been made in the p-type
PbTe. However, the n-type PbTe only shows a relatively low figure of merit ZT and …

We report n-type PbTe with a maximum ZT∼ 1.2 at 673 K and an average ZT ave∼ 0.84 at
300–823 K, which was achieved through a Sn and Se co-alloying approach. We find that the …

PbTe-based thermoelectric materials are considered to be a medium-temperature
thermoelectric candidates and the high-performance n-type PbTe is urgently to be …

Single elemental doped n-type PbTe compounds were successfully prepared with high
pressure synthesis followed by spark plasma sintering. Thermoelectric properties …

Forming solid solutions in PbTe based materials can simultaneously reduce lattice thermal
conductivity and engineer the band structure to enhance the electrical properties. In this …

Lead chalcogenides have long been studied as promising thermoelectric materials,
operating at the mid-temperature range of 500–950 K. Here, we studied thermoelectric …
