Abstract: A superconducting Josephson junction tunnel device having in particular lead alloy electrodes (Pb-In and Pb-In-Sn) and a very precisely defined and dense tunnel barrier comprising an oxide of the lead alloy electrode. Such devices can be thermally cycled between liquid helium temperatures and room temperatures, and provide large tunnelling currents.
