Title Electronic structure of rare earth oxides
Abstract The electronic structures of dioxides, REO2, and sesquioxides, RE2O3, of the rare earths, RE=Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy and Ho, are calculated with the self-interaction-corrected local-spin-density approximation. The valencies of the rare earth ions are determined from total-energy minimization. Ce, Pr, and Tb are found to have tetravalent configurations in their dioxides, while for all the sesquioxides the trivalent ground-state configuration is most favourable. Tetravalent NdO2 is predicted to exist as a metastable phase – unstable towards the formation of hexagonal Nd2O3. The trends of the band gap structure are discussed.
