      abstract     = {We investigated the possibility of tuning the local
                      switching properties of memristive crystalline SrTiO 3 thin
                      films by inserting nanoscale defect nucleation centers. For
                      that purpose, we employed chemically-synthesized Au
                      nanoparticles deposited on 0.5 $wt\%-Nb-doped$ SrTiO 3
                      single crystal substrates as a defect formation template for
                      the subsequent growth of SrTiO 3 . We studied in detail the
                      resulting microstructure and the local conducting and
                      switching properties of the SrTiO 3 thin films. We revealed
                      that the Au nanoparticles floated to the SrTiO 3 surface
                      during growth, leaving behind a distorted thin film region
                      in their vicinity. By employing conductive-tip atomic force
                      microscopy, these distorted SrTiO 3 regions are identified
                      as sites of preferential resistive switching. These findings
                      can be attributed to the enhanced oxygen exchange reaction
                      at the surface in these defective regions},
