Self-shunted Nb/AlOx/Nb Josephson junctions
We describe the fabrication and properties of high critical current density (Jc) Nb/AlOx/Nb Josephson junctions with deep-submicron dimensions. The junctions are fabricated using a planarized process in which all levels are patterned using a combination of optical and electron beam lithography. The base and counter electrodes are defined by reactive ion etching using quartz etch masks to give a...
متن کاملTransport properties of Nb/PdNi bilayers and Nb/PdNi/Nb Josephson junctions
The superconducting proximity effect was examined in both Nb/PdNi (SF) bilayer films and Nb/PdNi/Nb (SFS) Josephson junctions. In Nb/PdNi bilayer films, nonmonotonic behavior of Tc was observed as a function of PdNi thickness dF. The effective exchange energy Eex extracted from the data was about 13 meV. In Nb/PdNi/Nb (SFS) Josephson junctions, the existence of a crossover between the 0 state a...
متن کامل0-π oscillations in nanostructured Nb/Fe/Nb Josephson junctions
The physics of the π phase shift in ferromagnetic Josephson junctions enables a range of applications for spin-electronic devices and quantum computing. We investigate transitions from “0” to “π” states in Nb/Fe/Nb Josephson junctions by varying the Fe barrier thickness from 0.5 nm to 5.5 nm. From magnetic measurements we estimate for Fe a magnetic dead layer of about 1.1 nm. By fitting the cha...
متن کاملElectronic Cooling in Nb/AlOx/Al/AlOx/Nb Double Tunnel Junctions
Several recent papers have predicted the feasibility of superconducting tunnel junction-based electronic cryocooler devices operating in the temperature range 0.1 4K. We have extended previous work in stacked Nb/AlOx devices to investigate the nonequilibrium effects in them and to examine the influence of barrier conductance and layer thickness on the electronic cooling achievable by this techn...
متن کاملMicrocompression study of Al-Nb nanoscale multilayers
Microcompression tests were performed on the Al/Nb multilayers of incoherent interfaces with the layer thicknesses of 5 nm Al/5 nm Nb and 50 nm Al/50 nm Nb. The Al-Nb multilayers showed increase in strength as the layer thickness was reduced; the average flow stresses at 5% plastic strain from the 5 nm Al/5 nm Nb and 50 nm Al/50 nm Nb layer thickness specimens were determined to be 2.1 GPa and ...
