      abstract     = {The ability to tailor oxide heterointerfaces has led to
                      novel properties in low‐dimensional oxide systems. A
                      fundamental understanding of these properties is based on
                      the concept of electronic charge transfer. However, the
                      electronic properties of oxide heterointerfaces crucially
                      depend on their ionic constitution and defect structure:
                      ionic charges contribute to charge transfer and screening at
                      oxide interfaces, triggering a thermodynamic balance of
                      ionic and electronic structures. Quantitative understanding
                      of the electronic and ionic roles regarding
                      charge‐transfer phenomena poses a central challenge. Here,
                      the electronic and ionic structure is simultaneously
                      investigated at the prototypical charge‐transfer
                      heterointerface, LaAlO3/SrTiO3. Applying in situ
                      photoemission spectroscopy under oxygen ambient, ionic and
                      electronic charge transfer is deconvoluted in response to
                      the oxygen atmosphere at elevated temperatures. In this way,
                      both the rich and variable chemistry of complex oxides and
                      the associated electronic properties are equally embraced.
                      The interfacial electron gas is depleted through an ionic
                      rearrangement in the strontium cation sublattice when oxygen
                      is applied, resulting in an inverse and reversible balance
                      between cation vacancies and electrons, while the mobility
                      of ionic species is found to be considerably enhanced as
                      compared to the bulk. Triggered by these ionic phenomena,
                      the electronic transport and magnetic signature of the
                      heterointerface are significantly altered.},
