Abstract:
The feasibility of using the superconductive properties of certain thin film configurations to perform electronic functions was studied. Particular attention was paid to the use of thin film configurations involving electron tunneling between superconductors. The effect of crystalline anisotropy on the tunneling current vs voltage characteristic is being examined. Preliminary results were obtained using an aluminum tricrystal which contains in one specimen three single crystals each having as its surface one of the three principal crystallographic planes. Details of the sample preparation and the experimental apparatus are given. In another experiment, a thin film tunneling assembly was used as an RF detector to frequencies as high as 65 mc. The detection was most efficient at points on the dc characteristic of sharpest nonlinearity. Author
