| Research Abstract |
We have carried out experiments to explore anomalous phenomena in various Josephson junctions with a mechanically controllable break junction technique. The tunnel conductance between two metallic gold electrodes is found to be influenced by absorbed helium atoms. In niobium superconducting junctions, anomalous behavior of difference conductance has been observed. We pursue the research of Josephson devices with molecules following these results.
