Nov 24, 1997 · A Josephson junction is made by sandwiching a thin layer of a nonsuperconducting material between two layers of superconducting material.
In physics, the Josephson effect is a phenomenon that occurs when two superconductors are placed in proximity, with some barrier or restriction between them.
The principle of the dc Volt: Put 5000 Josephson junctions in series, and apply a fixed frequency, which can be done very accurately, and measure the interval of the resulting dc voltages that occur at precise voltage intervals.
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.
Jan 27, 2021 · Alex Braginski revisits beneficial consequences of the Josephson effect for science and economy, with a special focus on the impact of Josephson devices and circuits in many areas of science and in geophysical prospecting for minerals.
