                      formation and rupture in a solid electrolyte have attracted
                      much interest due to low switching voltages and a
                      prospective high scalability. In this study we indirectly
                      visualized the growth and dissolution of the conductive
                      filament in Ag-Ge-Se samples with Ag bottom electrodes by
                      surface analysis with Conductive Atomic Force Microscopy
                      (CAFM). By application of a negative voltage to the inert
                      CAFM tip, conductive filaments were grown on the scanned
                      area and they were dissolved under reversed bias. The local
                      conductivity changes directly corresponded to changes in the
                      topography, i.e. to the filament protrusion and dissolution.
                      Topography changes could be circumvented by limiting the
                      maximum current. By placing the CAFM tip on a random spot on
                      the sample, filaments with a diameter as low as 20 nm were
                      grown by local current-voltage measurements. (C) 2008
