Abstract : Superconducting line diodes were constructed by pressing a cylindrical film of oxidized tin against a plane film of oxidized tin. The 1-V characteristics at 1.5 degrees K were typical of superconducting point-contact and bridge junctions, and contained step structure indicative of Josephson self-resonances up to at least 1,200 GHz. Also, possible evidence of high-order quantum transitions was observed in the form of constant-voltage steps at voltages up to 47.6 mv. Two-junction experiments to determine the detector or emitter capability of the superconducting line diodes, yielded negative results. (Author)
