Cooperating on superconductivity

The results to date of a cooperative effort begun by AT&T, IBM, and MIT, called the Consortium for Superconducting Electronics (CSE), are reviewed. The goal is to bring high-temperature superconductivity to market rapidly. Of primary importance in these early years is the CSE's materials and processing program, which develops and evaluates substrate materials and film-deposition techniques for specific applications. Programs in junctions, microwave networks, and circuits are also underway. The aims and accomplishments of all four programs are examined. A successful trilayer approach is discussed. New members of the CSE are noted, and funding sources are indicated. >
