Positional disorder and diffusion path of oxide ions in the yttria-doped ceria Ce0.93Y0.07O1.96
Abstract
The scattering amplitude distribution of an yttria-doped ceria material (Ce0.93Y0.07O1.96, space group: Fmm) has been investigated between 23 and 1434 °C by the maximum-entropy method (MEM) combined with a Rietveld analysis using
