Self-powered electronic component and manufacturing method therefor

A self-powered Josephson junction device, comprising:

• a substrate formed of a single crystal of silicon;
• a layer of a superconductor epitaxially grown on the substrate, said superconductor layer being separated into two parts by a groove formed by a thin growth region and forming a Josephson junction;
• a layer of an insertion material forming the positive pole of the Josephson junction as well as the cathode of a microbattery deposited on the epitaxial layer at one side of the junction;
• a separator layer deposited on the epitaxial layer and over the thin layer of insertion material, said separator layer assuming the weak link of the Josephson junction;
• and
• a layer of an alkali metal providing an ion source and forming the anode of the microbattery deposited over the Josephson junction, covering the separator and extending into contact with the opposite side of said junction.
