Abstract

The mechanical and chemical processes occurring in undoped nanocrystalline CeO2 membranes due to order-disorder transition of oxygen vacancies were analyzed. 1.5±0.2 μm thick CeO2 films were deposited by radio frequency (RF) magnetron plasma sputtering on silicon. The nanocrystalline membranes were studied using x-ray diffraction analysis (XRD) and scanning electron microscopy (SEM). It was found that the order-disorder transition led to a large lateral expansion and buckling of the membranes.
