    Abstract

    A series of seven bulk crystals of Zn4+xSb3 (-0.12 ≤ x ≤ 0.12) are successfully prepared, and the relation between the Zn content and the thermoelectric properties is investigated. The sample with the nominal composition of Zn3.96Sb3 (x = -0.04) contain the maximum mass fraction of Zn4Sb3. The shapes of the S(T) and ρ(T) curves are drastically changed with varying x in the temperature range from 300 K to 700 K. Whereas the lower x leads to lower ρ, the magnitude of S unchanges, resulting in the fact that the power factor of the Zn-poor compositions in the Zn4+xSb3 system is lower than that of the Zn-rich compositions. The details of the influence of the Zn content and the scope of the improvement of the durability are discussed.
