Seebeck Coefficient of Cation-Substituted Disulfides CuCr1−x Fe x S2 and Cu1−x Fe x CrS2

Abstract

The effect of cation substitution on the Seebeck coefficient of CuCr1−x Fe x S2 (x = 0 to 0.30) and Cu1−x Fe x CrS2 (x = 0 to 0.03) in the temperature range of 100 K to 450 K has been investigated. Increasing iron concentration led to a metal–insulator transition which suppressed the thermoelectric power. However, for low iron concentration (x < 0.03), the Seebeck coefficient of CuCr1−x Fe x S2 and Cu1−x Fe x CrS2 exceeded the values for the undoped copper-chromium disulfide matrix CuCrS2 at temperature below 300 K.
