摘要

technique of construction of joints in josephson effect (fig. 2).1) achieved by the growth of a film biepitassiale of ybco and such that the barrier is obtained at the interface between an area of the film ybco, with orientation (110).deposited on a crystalline substrate srtio3 (110), and an area of the film of ybco with orientation (001) grown on a mgo film deposited directly on the substrate of srtio3.the values of the parameters and electronic device, in particular to the product icrn.this technique allows use of the advantages of manufacture for carrying type josephson junctions of ybco of good quality work at the temperature of liquid nitrogen.the technique presented allows us to integrate a large number of joints in a simple way, using the usual techniques fotolitografiche.
