Scheme of a flat interface between two superconducting bulks. Here label the left- and right-hand half-spaces. Two superconducting bulks which are separated by a layer of normal metal have misorientation . The two different geometries correspond to the different orientations of the crystals in the right- and left-hand sides of the interface. In the geometry (i) the plane on the right-hand side has been rotated around the -axis by . In the geometry (ii) the plane on the right-han side has been rotated around the -axis normal to the interface (-axis) by . For both of geometries (i) and (ii) we consider a rotation only in the right-hand superconductor and the crystallographic -axis in the left-hand half-space is selected parallel to the partition between the superconductors (-axis).
The component of the charge current (Josephson current) versus the phase difference for the order parameter (25), , and different thicknesses of the normal metal between superconductors. Here the part a of figure is for geometry (i) and part b is for geometry (ii). The currents are given in units of .
