Abstract

Cd_3-xA_xTeO₆(A= A³⁺ or A⁺) with a 1:1 ordered perovskite-type structure was carried out by a solid-state reaction method and heating mixtures of CdO, TeO₂, A₂O₃, respectively. The resistivity and thermoelectric power of the single-crystal indium-substituted sample were 0.6 mΩ cm and -50μV/K, respectively, giving a power factor of 4×10^-4 WK^-2m^-1, which is the highest among nontransition metal oxides.
