      abstract     = {Sm-doped ceria has one of the highest ionic conductivities
                      reported for rare earth-doped cerium oxides. The high
                      oxygen-ion conductivity can be attributed to the creation of
                      oxygen vacancies by doping and weak defect interactions
                      between oxygen vacancies and dopants. Especially, oxygen
                      vacancies in the nearest neighborhood to dopants decrease
                      the conductivity due to trapping and blocking. In this work,
                      the local structure around the Ce cations is investigated
                      using the extended X-ray absorption fine structure. The
                      resulting coordination numbers of cerium coordinated by
                      oxygen are only marginally larger than in a random oxygen
                      vacancy distribution, explaining the large ionic
                      conductivity.},
