The thermoelectric modules of π-shaped 1-, 2-, and 4-pairs are constructed using p-type Ca2.76Cu0.24Co4O9 and n-type Ca0.8Dy0.2MnO3 oxide materials. The reacted phases at the interfaces of the Ca2.76Cu0.24Co4O9/Ag electrode and Ca0.8Dy0.2MnO3/Ag electrode are not observed. The output powers of...

High-quality nano-sized Ce0.8Dy0.2O2−δ powders were synthesized by the solution combustion method, using C4H7NO4 (aspartic acid) as the combustion fuel. The nano-sized Ce0.8Dy0.2O2−δ powders provided an ultra-fine grain size and high density even at low sintering temperatures...

The incorporation of CeO2 and Dy2O3 to ZnO leads to a marked increase in the electrical conductivity. The absolute values of the Seebeck coefficients of Zn1−xCexO and Zn1−xDyxO increase with CeO2 and Dy2O3 contents up to x = 0.003 and 0.005, respectively, and then decrease with further...
