      abstract     = {We elucidated the formation process for
                      Ruddlesden-Popper-type defects during pulsed laser
                      deposition of Sr rich SrTiO3 thin films by a combined
                      analysis of in-situ atomic force microscopy, low energy
                      electron diffraction and high resolution scanning
                      transmission electron microscopy. At the early growth stage
                      of 1.5 unit cells, the excess Sr results in the formation of
                      SrO on the surface, resulting in a local termination change
                      from TiO2 to SrO, thereby forming a Sr rich (2 × 2)
                      surface reconstruction. With progressive SrTiO3 growth,
                      islands with thermodynamically stable SrO rock-salt
                      structure are formed, coexisting with TiO2 terminated
                      islands. During the overgrowth of these thermodynamically
                      stable islands, both lateral as well as vertical
                      Ruddlesden-Popper-type anti-phase boundaries are formed,
                      accommodating the Sr excess of the SrTiO3 film. We suggest
                      the formation of thermodynamically stable SrO rock-salt
                      structures as origin for the formation of
                      Ruddlesden-Popper-type antiphase boundaries, which are as a
                      result of kinetic limitations confined to certain regions on
                      the surface.},
