We report enhanced thermoelectric performance of SnTe by further increasing its intrinsic high carrier concentration caused by Sn vacancies in contrast to the traditional method. Along with In<sub>2</sub>Te<sub>3</sub> alloying, which results in an enhanced Seebeck coefficient, Li<sub>2</sub>Te is added to further increase the carrier concentration in order to maintain high electrical conductivity. Finally, a relatively high <i>PF</i> <sub><i>ave</i></sub> of ∼28 μW cm<sup>-1</sup> K<sup>-2</sup ...[more]
