abstract = {Cation-based resistive-switching memories rely on the
injection and drift of metal ions in nanoscale thin films.
In insulators that do not initially contain mobile cations,
such as SiO2, Ta2O5, and so forth, water redox reactions
occurring at the counter electrode (CE) were found to be
essential in enabling the dissolution of the active
electrode and to keep electroneutrality. In this study, we
report on the impact of the CE on redox processes prior to
resistive switching. Potentiodynamic measurements for
various electrode materials revealed that the catalytic
activity of the CE towards the water redox process
determines the concentration of dissolved ions within the
oxide and influences the rate of the total cell reaction.
This trend can be used as an indicator for the design of
both cation- and anion-conducting oxide-based
resistive-switching random-access memories.},
