Two-layer logic elements for classic cryogenic computers

In this paper, for the first time, two-layer logic elements "NOT", "AND", "OR" and "NOR" were manufactured, in which heating element of a nanowire one layer is located place where heated another superconductive nearest NbN layer. The film thickness (5-7 nm) was used to form superconducting nanowires different layers, Al 2 O 3 (25 as an interlayer dielectric. paper shows design elements, also demonstrates their operation pulse mode. use multilayer structures without galvanic coupling between allows multi-level devices. Keywords: thin films, contactless switching superconductor state, cryoelectronic devices, integrated cryogenic resistors, "NOT"/"AND"/"OR"/"NOR", computers.
