      abstract     = {We present a study of temperature dependent growth of
                      nano-sized ceria islands on a Cu (100) substrate. Low-energy
                      electron microscopy, micro-electron diffraction, X-ray
                      absorption spectroscopy, and photoemission electron
                      microscopy are used to determine the morphology, shape,
                      chemical state, and crystal structure of the grown islands.
                      Utilizing real-time observation capabilities, we reveal a
                      three-way interaction between the ceria, substrate, and
                      local oxygen chemical potential. The interaction manifests
                      in the reorientation of terrace boundaries on the Cu (100)
                      substrate, characteristic of the transition between oxidized
                      and metallic surface. The reorientation is initiated at
                      nucleation sites of ceria islands, whose growth direction is
                      influenced by the proximity of the terrace boundaries. The
                      grown ceria islands were identified as fully stoichiometric
                      CeO2 (100) surfaces with a (2 × 2) reconstruction.},
