Sep 17, 2019 · Josephson predicted the existence of tunnel currents carried by Cooper pairs for S \ (_L\) -I-S \ (_R\) junctions [1]. A series of phenomena identified as the Josephson effect are associated with this coherent passage of supercurrents [1, 2, 3, 17, 18, 19].

The Josephson effect (Josephson, 1962) is now used widely as a means of monitoring the absolute value of national standards of voltage maintained by standard cells to be related to frequency, f, and the Josephson constant 2elh; e is the charge on the electron and h is Planck's constant.
The DC Josephson effect. From the Josephson equations (5,6) it is clear that a DC current can be drawn through the junction without any voltage drop, as long as the DC current is smaller than I0. The phase difference will adjust according to equation (5).
