      abstract     = {Using first-principles density-functional-theory
                      calculations, we find a strong position and thickness
                      dependence of the formation energy of oxygen vacancies in
                      LaAlO3 vertical bar SrTiO3 (LAO vertical bar STO)
                      multilayers and interpret this with an analytical capacitor
                      model. Oxygen vacancies are preferentially formed at p-type
                      SrO vertical bar AlO2 rather than at n-type LaO vertical bar
                      TiO2 interfaces; the excess electrons introduced by the
                      oxygen vacancies reduce their energy by moving to the n-type
                      interface. This asymmetric behavior makes an important
                      contribution to the conducting (insulating) nature of n-type
                      (p-type) interfaces while providing a natural explanation
                      for the failure to detect evidence for the polar catastrophe
                      in the form of core level shifts.},
