The ability to cover large and complex areas with high-temperature superconducting material is required in many applications including patterned lines for microelectronics, complex shapes for resonators, and continuous coatings for power transmission lines. Thick film technology offers the ability to coat a variety of substrates by dipping, spraying, or screen printing. Silver and MgO substrates have been found to be chemically compatible with high-critical temperature superconducting thin films, but the compatibility of thermal expansion coefficients between film and substrate is also highly important when selecting a substrate. Electrical properties, such as critical current density and RF surface resistance, were used to evaluate the utility of these materials.
