Resumen

We examine the effect of interface disorder in suppressing superconductivity in coherently grown ultrathin
YBa2Cu3O7 (YBCO) layers on SrTiO3 (STO) in YBCO/STO superlattices. The termination plane of the STO
is TiO2 and the CuO chains are missing at the interface. Disorder (steps) at the STO interface cause alterations
of the stacking sequence of the intracell YBCO atomic layers. Stacking faults give rise to antiphase boundaries
which break the continuity of the CuO2 planes and depress superconductivity. We show that superconductivity
is directly controlled by interface disorder outlining the importance of pair breaking and localization by disorder
in ultrathin layers.
