Keywords:Surface proton conduction

We have prepared the Sm-doped CeO₂ thin film by RF magnetron sputtering and characterized its strucural and ionic conduction. The proton conduction below 350℃ increases with decreasing temperature. This contribites to the surface proton conduction proposed by Grtthus Machanism.
