Abstract

Since the discovery of superconducting tunneling and the Josephson effect in the early 1960’s, the electronic applications of superconductivity have advanced steadily and now comprise an emerging technology with a potential for large technical and economic impact. Digital circuits using the ultra-fast, low-power switching characteristics of Josephson junctions are potentially the basisof a new class of very high performance computers [1, 2, 3, 4]. Superconducting QUantum Interference Devices (or SQUID’s) have been commercially available for some time [5, 6]. Recent advances [7, 8] in the use of superconducting tunnel junctions as high frequency detectors of electromagnetic radiation have been sufficiently successful that serious applications in radio astronomy seem imminent. Finally, new levels of metrology and standards based on superconductivity are well established [6]. Thus, like the high-field, high-current electrical power related applications of superconductivity, the electronic applications of superconductivity present major opportunities. And while they both depend on the general advance of the knowledge of superconductivity and superconducting materials, they also present their own unique set of materials problems. In this chapter we discuss the materials aspects of superconducting electronics with the objective of establishing clearly the essential materials requirements, the state of the art of the technology, outstanding problems, and prospects for the future.
