Search for new substrate materials for high temperature superconducting thin films by Michael Matthews Hall Download PDF EPUB FB2

Substrate selection presents particular challenges for the production of high‐quality high‐temperature superconducting (HTS) thin films suitable for applications. Because the substrate is generally a passive component, it is often ignored and assumed to have Cited by: The best films that can currently be produced are grown High-Temperature Superconducting Thin Films on materials that have serious limitations.

The search for viable substrate materials is an active area of research. Significant breakthroughs are required to identify materials that satisfy all of the requirements that the HTS films by: 2. Temperature and field dependence of transport critical currents in high-temperature superconducting materials.

Technological implications. Summary and concluding remarks. References. Recommended reading. High-Temperature Superconducting Thin Films (J.M. Phillips). Thin-film fabrication.

Substrates. Multilayers. Characterization of HTS thin films. The high-quality YBCO thin films were deposited on the various single-crystal substrates such as LaAlO 3, SrTiO 3, MgO with typical electronic properties: superconducting transition temperature (T c) 90 K, critical current density (J c) 2–4 MA/cm 2 at 77 K in self-field and microwave surface resistance (R s) μΩ for 10 GHz at 77 K, which.

In addition, the most recent research results in the measurements, materials synthesis and processing, and characterization of physical properties of high-temperature superconductors are presented.

Researchers and students alike can use this book as a comprehensive introduction not only to superconductivity but also to materials-related.
