Thermoelectric properties of Sn1−x−yTiySbxO2 ceramics

Thermoelectric properties of Sn1−x−yTiy SbxO2 ceramics were investigated in detail. The addition of Sb into SnO2 matrix increased the electric conductivity, σ. The increase in the σ value should be caused by the increase in the carrier concentration. The Seebeck coefficients of all the samples were negative, which means that these samples have n-type conduction. The samples of this study have porous structure. The maximum Z value of all the samples measured in this study was 2.4 × 10−5 K−1.
