Tóm tắt

The moment method in statistical (SMM) dynamics is used to study the lattice constant of CeO2 thin films taking into account the anharmonicity effects of the lattice vibrations. The nearest neighbor distance and the lattice constant of CeO2 thin films are calculated as a function of temperature. SMM calculations are performed using the Buckingham potential for the CeO2 thin films. 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. The authors 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.
