This review provides a theoretical basis for understanding the current-phase relation (C⌽R) for the stationary (dc) Josephson effect in various types of superconducting junctions. The authors summarize recent theoretical developments with an emphasis on the fundamental physical mechanisms of the deviations of the C⌽R from the standard sinusoidal form. A new experimental tool for measuring the C⌽R is described and its practical applications are discussed. The method allows one to measure the electrical currents in Josephson junctions with a small coupling energy as compared to the thermal energy. A number of examples illustrate the importance of the C⌽R measurements for both fundamental physics and applications.

“…The latter fact indicates that the true potential of this process has not yet been reached [20]. AlN tunnel barriers produced with this technique are promising candidates for utilization in double tunnel barrier junctions for digital applications, since a very high transmissivity and quality of the tunnel barriers are also required for this application [21], [22].…”

Abstract-We characterize the fabrication process of superconductor-insulator-superconductor junctions (SIS) based on a Nb/Al-AlN /Nb tri-layer. Utilization of the AlN tunnel barrier, produced by Al nitridation in a nitrogen glow discharge, enables us to produce high quality SIS junctions with low values (the product of junction resistance and area). Analyzing the correlation of junction resistance and plasma properties, it is concluded that the mechanism of tunnel barrier formation is based on nitrogen implantation into the Al layer with subsequent diffusion of nitrogen, stimulated by plasma heating. The latter process plays a dominant role since values are well correlated with the power dissipated on the substrate surface. An SIS mixer using this technology and electron-beam lithography has been successfully fabricated.

“…Compatible with the well-established Nb-A1 technology [a], [3], the SINIS conception is also suitable for cryoelectronic applications requiring a high level of integration and a small parameter spread, e.g. voltage standards [4], [5] and rapid single flux quantum logic circuits [6].…”

Il'ichev, Hans Eclthardt Hocnig, arid Hans-Gcorg Meyer A6struct-The supercurrent-phase relation (CPR) of Nb-A1 based Josephson elements of superconductor/insulator/ normal conductor/insulator/superconductor-type is deduced from impedance measurements of the phase-biased junction. The chosen temperature range from 1.9 to 8.0 K covers the superconducting transition of the aluminum interlayer below which a pronounced non-harmonic CPR is found. At temperatures higher than the corresponding critical temperature, the CPR did not deviate significantly from purely harmonic shape. Both results are in agreement with theoretical predictions.
