Abstract

We report the fabrication and thermoelectric properties of a multi-layered unicouple of [Ca₂CoO_3-δ]_0.62CoO ₂ (Ca349; p-type) and Ca_0.9La_0.1MnO _3-δ(Mn113; n-type). The multilayered thick films consisting of Ca349, Mn113 and Al₂O₃ were prepared using an Electrophoretic deposition (EPD) method. In particular, the Ca349 layer was deposited under a magnetic field of 3 T and strongly c-axis-grain-oriented microstructure was obtained. The unicouple of hot-forged Ca349 and Mn113 layers generated 85 mV of voltage in ΔT -450 K and, however, showed remarkably high internal resistance due to porous microstructure of the Mn113 layer. The development of a densification process for the n-type layer is an important for improving higher power density.
