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.engjournal articlehttp://prb.aps.org/abstract/PRB/v87/i24/e245105open access537.312.62SuperconductivityFísica del estado sólido2211 Física del Estado Sólido
