Abstract

Abstract Polycrystalline nonstoichiometric Yb14MnSb11 compounds have been successfully prepared by modified induction melting and spark plasma sintering. The carrier concentration was finely tuned by changing the elemental ratio of Mn to Sb. Excess Mn decreases the electrical conductivity and increases the Seebeck coefficient. The thermal conductivity of all samples was less than 1.0 W m–1 K–1. The maximum ZT value is 0.35 K at 673 K for Yb14Mn1.05Sb11, significantly higher than that of the stoichiometric Yb14MnSb11 polycrystalline sample. (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
