                      interfaces for nonvolatile memory applications are
                      investigated by hard x-ray photoelectron spectroscopy
                      (HAXPES) and DC transport measurements, using acceptor doped
                      SrTiO3 as a model memristive oxide. Metal-insulator-metal
                      (MIM) structures with a noble metal (Pt) top electrode form
                      a Schottky barrier and exhibit rectifying properties, while
                      a reactive metal (Ti) as top electrode shows symmetric I(V)
                      characteristics and a flat band situation at the interface.
                      The transition from rectifying to ohmic I(V) relations with
                      increasing Ti thickness is discussed with respect to the
                      electrochemical reaction at the interface, the band
                      alignment at the electrode/oxide interface, and the slope of
                      the energy bands across the MIM structure.},
