Thin Film Studies of the Proximity Josephson Effect
Abstract
The topics of theoretical and experimental interest in this research have been: The Proximity Induced Josephson Effect (PIJE), an effect occurring at a Normal Metal/Superconductor (N/S) interface which displays many of the features of the Josephson effect, the device potential of which has not been at all explored. The design and construction of a cryogenic scanning tunneling microscope capable of operating in ultra high vacuum. The Proximity Induced Josephson Effect (PIJE) has been observed at a Normal Metal/Superconductor (N/S) interfaces in point contact NS systems, and displays features resembling the Josephson effect. In experiments with Nb and Ta probes contacting MO and UBe13 (normal state) surface, the I(V) exhibit a low resistance segment centered at zero bias current resembling a Josephson current with a small series resistance R*, which has been interpreted as a spreading resistance in the normal state electrode.
