Lattice constant of CeO2

Purpose: The purpose of thesis is to study the influence of temperature, pressure and dopant on the diffusion coefficient and ionic conductivity of the bulk material as CeO2, c-ZrO2, YDC and YSZ. For YDC and YSZ thin films, we find the thickness dependence of the lattice constant, diffusion coefficient and ionic conductivity

Some thermodynamic quantities of ZrxCe1-xO2/CeO2 systems are investigated by using the moment method in statistical dynamics taking into account the anharmonicity effects of lattice vibrations. The analytic expression of the Gibbs free energy, Helmholtz free energy, and specific heats at the constant volume of ZrxCe1-xO2/CeO2 systems are obtained.

In the present study, the influence of temperature and the size of the lattice constant of CeO2 thin film have been studied using three different interatomic potentials. We discuss temperature and thickness dependence of the lattice constant of CeO2 thin films and we compare our calculated results with those of the experimental results.
