Objectives and Approach

Superconductivity above the temperature of liquid nitrogen in the YBa[2]Cu[3]O[7] family (YBCO) compounds, and more generally in high-T[c] superconducting oxides (HTSO), allows the development of superconducting electronics working at reasonable temperature. Subsequent improvement of electronic properties, such as very fast circuits, may be of importance for information technology and microelectronics. The fundamental building block of most superconducting microelectronic devices involved in information technology is the Josephson junction.

The goals of this project were to:

Progress and Results

The following results were obtained:

These technological results, added to the work on simulation, constitute a strong basis for improving the Union's ability to produce IT devices based on controlled high-T[c] superconductor thin-film technology. The work is being continued in project 6677, UNITED II.
