Book Description
The DuPont program was successful in generating useful knowledge about thallium cuprate materials, photoresist reflow processing, and radiant heater technology though it did not lead to a new junction technology. Among the achievements of this program was the in situ fabrication of both (Tl, Pb)Sr2CuO5 and (Tl, Pb)Sr2Ca(1-x)Y(x)Cu2O7 films on full two inch wafers. These films were uniform in properties and had quite smooth surfaces as predicted. We were also able to qualify cerium oxide as compatible with the in situ growth process and suitable in a thallium-based multilayer technology. In addition, this project resulted in the first-ever epitaxial thallium cuprate films with copper oxide sheets oriented out of the plane of the film. The program has determined that standard HTS substrates, NdGaO3, CeO2- buffered Al2O3, and LaAlO3, are not ideal for an in situ thallium cuprate junction technology Moreover, we have found that (Tl, Pb) Sr2Ca(1-x)Y(x)Cu2O7 can be as susceptible to electromigration as YBa2Cu3O7. The potentially greater stability of (Tl, Pb)Sr2Ca(1-x)Y(x)Cu2O7 was considered to be one of the key benefits of developing this new technology. In conclusion, the development of stable, reproducible multilayer SNS junctions is no more likely to be achieved with the thallium lead cuprates than with any other HTS materials system.

Book Description
The work carried out under this grant has been the investigation of thin films and single crystals of the layered cuprate high-temperature superconductors, as well as other model systems. A primary objective in the program was the development of a better understanding of the limits of the occurrence of superconductors with high transition temperature (above liquid nitrogen temperature). The work is thus composed of an empirical part that searches for superconductivity by similarities and chemical guidance as well as critical tests for various theories of the high-Tc mechanism. Another aspect of the program was to study the superconducting and normal state properties in applied magnetic fields, in particular we studied the coupling between the Cu-O layers in superlattices. We employed the artificially layered Superconductor/ insulator system of MoGe/Ge which have in-plane and out-of plane anisotropies which bracket those found in the layered cuprates model system.
