Submicron YBCO Josephson junctions on sapphire bicrystal substrates for microwave devices

Submicron YBCO bicrystal Josephson junctions (JJ) and devices for high frequency applications were designed, fabricated and experimentally studied. The key elements of these devices are bicrystal sapphire substrates with symmetric misorientation angles 14.2 , 18.4 and 24 which were fabricated by a solid-state intergrowth method. A technological process based on deep ultraviolet photolithography...

SIS junctions with frequency dependent damping for a programmable Josephson voltage standard

Experimental and computational results on programmable Josephson junction array (JJA) chips based on superconductor-insulator-superconductor (SIS) junctions are presented. Implications of circuit design and fabrication process on the performance are discussed. We introduce a method to decrease the attenuation of the pump microwave. Different designs are compared, suggesting that 1 V chips opera...

3He Josephson Junctions

The flow of superfluid 3He-B through a 65 3 65 array of nanometer-size apertures has been measured recently by Backhaus et al. They find in the current-phase relation a new branch, the so-called p state. We study two limiting cases which show that the p state arises from the coupling of the phase degree of freedom to the spin-orbit rotation. The p state exists in a single large aperture, but is...

Josephson junctions in charge and phase picture Theory and applications

Properties of weak links between two superconductors, or Josephson junctions, make them interesting for fundamental physics research. Since their discovery over four decades ago, they have provided a unique way to study the behavior of the superconducting quantum phase. More recently, ultra small, or mesoscopic, Josephson junctions with substantial single Cooper pair charging energy have gained...

On kink-dynamics of Stacked-Josephson Junctions

Dynamics of a fluxon in a stack of coupled long Josephson junctions is studied numerically. Based on the numerical simulations, we show that the dependence of the propagation velocity c on the external bias current γ is determined by the ratio of the critical currents of the two junctions J .
