Abstract

Polycrystalline In ₂O ₃ ceramics co-doped with Zn and Nd were prepared by the spark plasma sintering (SPS) process, and microstructure and thermoelectric (TE) transport properties of the ceramics were investigated. Our results indicate that co-doping with Zn ²⁺ and Nd ³⁺ shows a remarkable effect on the transport properties of In ₂O ₃-based ceramics. Large electrical conductivity (∼130 S cm ^-1) and thermopower (∼220 μV K ^-1) can be observed in these In ₂O ₃-based ceramic samples. The maximum power factor (PF) reaches 5.3 × 10 ^-4 W m ^-1 K ^-2 at 973 K in the In _1.92Nd _0.04Zn _0.04O ₃ sample, with a highest ZT of ∼0.25.
