Аннотация:A study has been made of the current-voltage characteristics of break junctions in BiSrCaCuO-Pb samples containing 2-2-1-2 and 2-2-2-3 phase intergrowths. The current-voltage characteristics of these break junctions have a region in which the current rises vertically, at Vg = ± 2Δ/ e. They also have the knee typical of S1-S2 - I-S2-S1 tunnel structures. The temperature dependence of the gap parameter Δ of these samples indicates a strong proximity effect
