      abstract     = {Perovskites such as SrTiO3, BaTiO3, and CaTiO3 have become
                      key materials for future energy-efficient memristive data
                      storage and logic applications due to their ability to
                      switch their resistance reversibly upon application of an
                      external voltage. This resistance switching effect is based
                      on the evolution of nanoscale conducting filaments with
                      different stoichiometry and structure than the original
                      oxide. In order to design and optimize memristive devices, a
                      fundamental understanding of the interaction between
                      electrochemical stress, stoichiometry changes and phase
                      transformations is needed. Here, we follow the approach of
                      investigating these effects in a macroscopic model system.
                      We show that by applying a DC voltage under reducing
                      conditions on a perovskite slab it is possible to induce
                      stoichiometry polarization allowing for a controlled
                      decomposition related to incongruent sublimation of the
                      alkaline earth metal starting in the surface region. This
                      way, self-formed mesoporous layers can be generated which
                      are fully depleted by Sr (or Ba, Ca) but consist of titanium
                      oxides including TiO and Ti3O with tens of micrometre
                      thickness. This illustrates that phase transformations can
                      be induced easily by electrochemical driving forces.},
