| Outline of Final Research Achievements |
We have carried out experiments to explore anomalous phenomena in various nano-contacts with a temperature controlled break junction. In niobium superconducting junctions, normal-metal/superconductor junctions have been achieved with a heater placed in one side of the contacts. The tunnel conductance between two metallic gold electrodes is found to be influenced by absorbed helium atoms. We pursue the research of superconducting devices with molecules following these results.
