Thermoelectric Properties of High‐Entropy Wolframite Oxide: (CoCuNiFeZn)<sub>1−<i>x</i></sub>Ga<sub><i>x</i></sub>WO<sub>4</sub>
Abstract
<jats:p>Herein, the synthesis of high‐entropy wolframite oxide (CoCuNiFeZn)<jats:sub>1‐<jats:italic>x</jats:italic></jats:sub>Ga<jats:italic>x</jats:italic>WO<jats:sub>4</jats:sub> through standard solid‐state route followed by spark plasma sintering and their structural, microstructural, and thermoelectric (TE) properties are investigated. X‐ray diffraction pattern followed by patterns matching refinement shows a monoclinic structure with the volume of the unit cell decreasing with increasing Ga content. The optical bandgap for these oxides shows a cocktail effect in high‐entropy configuration. The Seebeck coefficient indicates electrons as dominating charge carriers with a nondegenerate behavior. The electrical resistivity decreases with increasing temperature depicting a semiconducting nature. Thermal conductivity in high‐entropy samples (<jats:italic>κ</jats:italic> ≈ 2.1 W m<jats:sup>−1</jats:sup> K<jats:sup>−1</jats:sup> @ 300 K) is significantly lower as compared to MgWO<jats:sub>4</jats:sub> (<jats:italic>κ</jats:italic> ≈ 11.5 W m<jats:sup>−1</jats:sup> K<jats:sup>−1</jats:sup> @ 300 K), which can be explained by the strong phonon scattering due to large lattice disorder in high‐entropy configuration. The TE figure of merit <jats:italic>zT</jats:italic> increases with Ga doping via modifying all three TE parameters positively.</jats:p>
