- When there is a fixed cross around the junction, the phase and values for the same will alter linearly in accordance with time. Owing to this, the current will be a sinusoidal AC (Alternating Current) with a certain amplitude and frequency.

The Josephson effect produces a current, known as a supercurrent, that flows continuously without any voltage applied, across a device known as a Josephson junction (JJ). These consist of two or more superconductors coupled by a weak link.

May 29, 2024 · Discovered in 1962 by British physicist Brian Josephson, it relates to the behavior of a supercurrent (a current that flows indefinitely long without any resistance) across two superconducting materials separated by a very thin non-superconducting barrier.

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].

Introduction. In 1962, B.D. Josephson analysed what happens at a junction between two closely spaced superconductors, separated by an insulating barrier. If the insulating barrier is thick, the electron pairs can not get through; but if the layer is thin enough (approximately 10 nm) there is a probability for electron pairs to tunnel.
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 2 elh; e is the charge on the electron and h is Planck's constant.
