We will conduct a two-year project to study the fundamental issues relating to the electronic and material properties of Gd-doped, Sm-doped, and Yb-doped CeO2 thin films. In order to resolve the behavior of the ionic conductivity at medium temperature, three major tasks are planned, including the synthesis and study the formation mechanisms of CeO2 fiber and various thin films; The atomic structure simulation of doped CeO2 on the ionic conductive phenomena; The measurement of electronic conductivity of various films in redox and medium-temperature conditions.氧化鈰離子導電釤釓ceriaionic conductivitysamariumgadolinium
