Superconducting transistor

Abstract

Abstract PURPOSE:To eliminate heat build-up and enable a large current to be taken out without interrupting high integration by providing a first electrode on a substrate, a superconductor layer on it, and then a second electrode. CONSTITUTION:The first conductive electrode 9 consisting of Al, a Y-Ba-Cu-O system superconductive layer 10, and the second electrode 11 consisting of Al are provided on a glass substrate 8. Then, an insulation film between layers 12 consisting of SiO2 is formed on it. A source electrode 13 and drain electrode 14 consisting of Al are connected to a superconductive layer 10. Flow of current exceeding threshold value of the superconductive layer 10 from the first electrode 9 to second electrode 11 allows the channel are to be in a highly insulated status with large resistance and current flowing between the electrodes 9 and 11 controls current flowing between the source and drain electrodes 13 and 14.
