AB We examine the effect of interface disorder in suppressing superconductivity in coherently grown ultrathinYBa2Cu3O7 (YBCO) layers on SrTiO3 (STO) in YBCO/STO superlattices. The termination plane of the STOis TiO2 and the CuO chains are missing at the interface. Disorder (steps) at the STO interface cause alterationsof the stacking sequence of the intracell YBCO atomic layers. Stacking faults give rise to antiphase boundarieswhich break the continuity of the CuO2 planes and depress superconductivity. We show that superconductivityis directly controlled by interface disorder outlining the importance of pair breaking and localization by disorderin ultrathin layers.
