Evaluation of the Defect Cluster Content in Singly and Doubly Doped Ceria through In Situ High-Pressure X-ray Diffraction

Abstract

) size; their amount, distribution, and spatial correlation can be interpreted as a complex interplay between the defects' binding energy, nucleation rate, and growth rate. The synoptic analysis of data derived from all of the considered systems also suggests that the detection limit of the defects by X-ray diffraction is correlated to the defect size rather than to their amount, and that the vacancies' flow through the lattice is hindered by defects irrespective of their size and association degree.
