The disclosure relates to a Josephson junction formed by a non-superconducting barrier between two superconducting films of the (R) BaCuO (R=rare earth) group. In order to take advantage of the greater coherence length of superconductors along the CuO planes, i.e. perpendicularly to the long axis 'c' of the crystal unit cell, the superconducting film is oriented so that the axis 'c' is parallel to the plane of the junction. The device can be applied to Josephson junctions and to SQUIDs.

Disclosed is a device made of superconductive material wherein the superconducting layer is enclosed by at least one material which is a conductor of ions of one of the anionic constituent elements of the superconductive layer. This makes it possible to adjust the stoichiometry of the superconductive layer. The disclosure also concerns a method for adjusting the content of the constituent elements of the superconductive layer by electrolysis.

A method for making a layer of monocrystalline, semiconducting material on a layer of insulating material is disclosed. For this, epitaxial growth is achieved in a cavity closed by layers of dielectric materials, using seeds of monocrystalline, semiconducting material of a substrate. This method thus enables a 3D integration of semiconductor components.
