“…The dual doping of aluminum and gallium increases the power factor of zinc oxide to 0.65 at 1247 K 6 . Simultaneous substitution of multiple dopants such as Ni, S, C, and Fe resulted in to 2.4 times increase in the figure of merit with 60% increase in power factor 24 . Ullah et al reported 1.4 times increment in power factor of Al and Ga dual doped ZnO ceramics 25 .…”

Effect of structural and morphological deformation on the enhancement of thermoelectric properties of zinc oxide due to the dual substitution of indium and nickel was investigated. The doped materials resemble the hexagonal wurtzite structure of the host material, with increased crystallite size and strain, indicating the inclusion of the cations with larger radius. Reduction in the optical band gap energy from 3.1 eV to 2.20 eV is observed with a red shift in the absorption edge. The donor cations doped samples have high charge carrier density, resulting an increase in the transport properties. Highest electrical conductivity and seebeck coefficient were obtained for the doped samples leading to a hike in the power factor of 1427 μW/mK 2 . The thermal conductivity decreased with doping concentration, and highest figure of merit of 0.11 was obtained.

“…The p-type TEs include Ca 3 Co 4 O 9 [10][11][12][13][14][15], Na x CoO 2 [16][17][18][19], and BiCuSeO [20][21][22]. The n-type TEs contain SrTiO 3 [23][24][25][26][27], CaMnO 3 [28,29], CaTiO 3 [30,31], In 2 O 3 [32,33], and ZnO [34,35], etc. As presented in Figure 1, most ZT values of the oxide TEs are smaller than 1.0 and have an urgent demand for optimizing their performance to meet the broad and efficient recycling of energy.…”

Thermoelectric materials have gained wide attention to realize multilevel efficient energy management to alleviate the increasingly severe energy crisis. Oxide ceramics were well-explored as potential thermoelectric candidates because of their outstanding merits, including abundance, eco-friendliness, high-temperature stability, and chemical stability. In this work, we aim to provide a comprehensive summary of the diversified state-of-the-art oxide ceramics and establish the links between composition designing, preparation process, structural characteristics, and properties to summarize the underlying chemistry and physics mechanism of band engineering, doping, composited with the second phase, defects engineering, and entropy engineering. Furthermore, advanced device design and applications such as thermoelectric modules, miniature generators, sensors, and coolers were reviewed. Ultimately, the challenges and future perspective of oxides ceramics for the device design and thermoelectric applications in the development of energy harvesting technology have been prospected.
