Carrier and Phonon Engineering in Sb‐Doped Sn0.8Mn0.1Pb0.1Te: A Pathway to Superior Thermoelectric Performance

Rare Metals, EarlyView.
ABSTRACT SnTe is considered a potential alternative to PbTe for thermoelectric applications. However, excessive carrier concentration and thermal conductivity result in poor thermoelectric performance. Herein, p‐type SnTe‐based materials Sn0.8‐xMn0.1Pb0.1SbxTe were synthesized, and the combined effects of Sb, Mn, and Pb were systematically investigated.
