FIELD: electrical engineering including superconductivity; improved technologies for producing semiconductors.
SUBSTANCE: when specimen of desired size is produced from working charge, it is pierced with thin threads, such as silk ones, disposed in parallel with direction of current flow in product so as to raise superconducting junction temperature; during heat treatment these threads burn out to form superconducting passages due to free movement of conducting electrons.
EFFECT: enhanced temperature of superconducting junction.
