      abstract     = {Exploiting the electronic charge-transfer across oxide
                      interfaces has emerged as a versatile tool to tailor the
                      electronic and magnetic properties of oxides. Such
                      charge-transfer concepts have been applied to drive
                      insulating oxides into metallic states, to trigger magnetism
                      in non-magnetic oxides, and to render gate-tunable
                      low-dimensional superconductors. While the richness in the
                      electronic and magnetic properties of these systems is the
                      main focus of research, the implications for the ionic
                      transport at oxide interfaces have not received much
                      attention so far. In this communication, we propose that
                      charge-transfer strategies can also be applied to boost
                      ionic charge carrier concentrations at interfaces by orders
                      of magnitude. Based on numerical space-charge modeling, we
                      will illustrate how the ‘p-type’ charge-transfer
                      predicted between SrO-terminated SrTiO3 and LaAlO3 may
                      foster 2-dimensional oxygen ion conduction at the interface.
                      The ion conduction is effectively separated from impurity
                      dopants, which may allow large concentrations of oxygen
                      vacancies to be achieved in the absence of trapping
                      phenomena. The interface promises high ionic conductivity
                      with nanoscale confinement, potentially allowing the design
                      of field-tunable ionic devices.},
