چکیده انگلیسی
Polycrystalline samples and thin films of the x = 0.8 member of the CexGd1âxO2ây solid solution have been successfully prepared. Their structural and transport properties have been studied by means of X-ray diffraction and electrical conductivity measurements as a function of preparation route, grain size, substrate nature and film thickness. Our data shows that the substrate roughness plays a relevant role in affecting the final Ï; however, by optimizing the thin films preparation conditions we showed that the conductivity of CGO material is always greater than that of the state-of-the-art oxide conductor, the YSZ 8 mol%, even though an electronic contribution ranging from 10% to 20% was found.
