Abstract
In this paper, single-phase polycrystalline beta-Zn4Sb3 samples were prepar ed by vacuum melting, and subjected to characterization using X-ray diffrac tion. The transport properties of the samples were measured between room te mperature and 723 K. The power factor was found to be high between 500 and 650 K, and a maximum value of 3.9 X 10(-4) W m(-1) K-2 was obtained at 623 K. The result suggested that this relatively inexpensive material is very p romising for thermoelectric applications. (C) 2000 Elsevier Science B.V. Al l rights reserved.
