Manipulating Peierls-Nabarro stress to realize extraordinary thermoelectric performance in n-type PbTe

PbTe is recognized as one of the best intermediate-temperature thermoelectric materials; however, its commercial applications are largely restricted by the comparatively lower performance of its n-type counterpart. Here we show that Peierls-Nabarro stress is manipulated through solute-induced lattice softening, which g...
