Beyond Ce–U Charge Transfer: Strain and Polarons in Epitaxial Ce1– x U x O2(111)

Abstract The redox chemistry of mixed ceria-based oxides is commonly interpreted in terms of direct charge transfer between neighboring cations. In the Ce1–xUxO2 system, this corresponds to the oxidation of U4+ into U5+ accompanied by the reduction of Ce4+ into Ce3+. In this work...
