Abstract

We report thermoelectric (TE) properties of mono-layer thick films of p-type [Ca 2 CoO 3-δ ] 0.62 CoO 2 (Ca349) and n-type compounds of Ca 0.9 La 0.1 MnO 3 (Mn113) and LaNi 0.98 Mo 0.02 O 3 (Ni113) for the improvement of TE performance in multi-layered TE modules. In the case of magnetically aligned Ca349 film, the improvement of TE properties due to the reduction of resistivity (ρ) was achieved by optimization of hot-pressing temperature and ρ was sensitive to relative density of the Ca349 layer. For the decrease in ρ of the n-type layers, two different approaches, the choice of Ni113 as a n-type compound and usage of fine powders of Mn113, were attempted. Both approaches were effective for reducing ρ even in the sintering at ̃900°C.
