Dopant site selectivity in BaCe0.85M0.15O3-δ by extended x-ray absorption fine structure [PDF]

open access: yes, 2005
Rare earth doped BaCeO3 has been widely investigated as a proton conducting material. Trivalent dopants are generally assumed to fully occupy the Ce4+-site, and thereby introduce oxygen vacancies into the perovskite structure. Recent studies indicate the
