SUPERCONDUCTIVE EFFECTS IN THIN FILMS.
Abstract
This report covers a two year effort in an applied research program to investigate the feasibility of using the superconductive properties of certain thin film configurations to perform electronic functions. Particular attention was paid to the phenomenon of electron tunneling between superconductors as exhibited in suitably prepared thin film structures. Stimulated by the extreme non-linearity of the I-V characteristic of a tunneling sample, investigations were carried out involving the use of such samples as detectors and mixers at rf and microwave frequencies. Detection experiments were carried out at 2 Mc, and the characteristic analyzed successfully by a simple model based upon an equivalent circuit representation of the tunnel structure. Use of a tunneling sample as an RF oscillator and amplifier by other workers is discussed and comments are made on the suitability of tunneling samples for practical applications. (Author)
