Zintl compounds are considered to be potential thermoelectric materials due to their "phonon glass electron crystal" (PGEC) structure. A promising Zintl-phase thermoelectric material, 2-1-2-type Eu<sub>2</sub>ZnSb<sub>2</sub> (<i>P</i>6<sub>3</sub>/<i>mmc</i>), was prepared and investigated. The extremely low lattice thermal conductivity is attributed to the external Eu atomic layers inserted in the [Zn<sub>2</sub>Sb<sub>2</sub>]<sup>2-</sup> network in the structure of 1-2-2-type EuZn<sub>2</su ...[more]
