WebAbstract. We have fabricated tunnel junctions on thin films of Y 1 Ba 2 Cu 3 O 7 which were epitaxially grown by magnetron sputtering on (100) and on (110) oriented SrTiO 3 substrates. These junctions of the type Y 1 Ba 2 Cu 3 O 7 /barrier/Pb or In showed with high reproducibility in the conductance a gap-like structure with the maxima near±16mV. Webfilms as different thickness have polycrystalline in nature and monoclinic structure . Figure (1)XRD pattern of CuO thin films at thickness (100-150-200)nm.
