      abstract     = {Experimental pulse lengthpulse voltage studies of SrTiO3
                      memristive cells are reported, which reveal nonlinearities
                      in the switching kinetics of more than nine orders of
                      magnitude. The results are interpreted using an
                      electrothermal 2D finite element model. The nonlinearity
                      arises from a temperature increase in a few-nanometer-thick
                      disc-shaped region at the Ti electrode and a corresponding
                      exponential increase in oxygen-vacancy mobility. The model
                      fully reproduces the experimental data and it provides
                      essential design rules for optimizing the cell concept of
                      nanoionic resistive memories. The model is generic in
                      nature: it is applicable to all those oxides which become
                      n-conducting upon chemical reduction and which show
                      significant ion conductivity at elevated temperatures.},
