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 …

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

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 …

Although Ga doping can weaken the electron phonon coupling in n-type PbTe, Ga-doped
PbTe has a relatively low carrier concentration (n) and high lattice thermal conductivity (κlat) …

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 …

The strong correlation between Seebeck coefficient and electrical conductivity is a main
bottleneck in enhancing the performance of thermoelectric materials. It indicates that optimal …

The inferior thermoelectric performance of n-type PbTe limits the overall conversion
efficiency in PbTe-based thermoelectric devices. Here, we introduce Sb and Cu 2 Te into n …

To achieve high‐performance n‐type PbTe‐based thermoelectric materials, this work
provides a synergetic strategy to improve electrical transport property with indium (In) …

A high ZT (thermoelectric figure of merit) of≈ 1.4 at 900 K for n‐type PbTe is reported,
through modifying its electrical and thermal properties by incorporating Sb and S …
