dc.description.abstractEffects of Li doping on the electrical properties were investigated. The Ce-0.75(Gd0.95-xLixCa0.05) O-0.25(2-delta) (x = 0, 0.01, 0.02, 0.03, 0.04, 0.05 mol%) thick films were sintered at 1400 degrees C for 8 h. X-ray diffraction (XRD) showed typical XRD patterns of a cubic fluorite structure and ionic conductivity was examined by AC impedance spectroscopy. From the experimental results, it was observed that the composition Ce-0.75(Gd0.95-xLixCa0.05)(0.25)O2-delta (x = 0.04 mol%) thick film electrolytes had higher conductivity and minimum activation energy at 600 degrees C and this can be explained by the increase in the oxygen vacancy concentration in the grain boundary.-
