Abstract
The following chapter contains the results on the Gd2O3 thin films on polycrystalline ceria substrates. The samples were prepared to investigate microstructure evolution and cation interdiffusion at the Gd2O3/CeO2 interface. Structure identification was performed and compared to structural findings of previous studies. Subsequently, concentration profiles across Gd2O3/CeO2 interfaces were measured to investigate the miscibility of Gd in CeO2 and to determine the cation interdiffusion coefficient at temperatures ranging from 986°C to 1175 °C. This allowed the calculation of the activation enthalpy of interdiffusion using an Arrhenius type relation.
