چکیده

This paper is concerned with high-T, superconducting compounds produced by metal-organic chemical vapour deposition. The nanostructure of different types of interfaces yttria stabilized zirconia buffer / (l-102)-sapphire substrate, YBazCu307-, film / Y2O3 precipitates as well as YBa2Cu307-, film / (001)-NdGa03, -SrTiO3, and -MgO substrates has been investigated by high resolution electron microscopy. The orientation relationships and the corresponding layer sequences across the interfaces have been determined with the aid of computer simulations.

On-line characterization of YBCO coated conductors using Raman spectroscopy methods.

The use of Raman spectroscopy for on-line monitoring of the production of superconducting YBa2Cu3O6+X (YBCO) thin films on long-length metal tapes coated with textured buffer layers is reported for the first time. A methodology is described for obtaining Raman spectra of YBCO on moving tape exiting a metal-organic-chemical-vapor-deposition (MOCVD) enclosure. After baseline correction, the spect...

Development and Characterization of Thin Film Superconducting Radio Frequency Surfaces for Accelerator Cavities

Superconducting thin films have the potential to improve the performance of particle accelerators. Before these thin films can be implemented, a systematic study on structureproperty correlations is necessary. Here, we present the characterization of niobium thin films deposited onto both ceramic and metallic substrates. In particular, the film microstructure and superconducting properties are ...

The quest towards epitaxial BaMgF4 thin films: exploring MOCVD as a chemical scalable approach for the deposition of complex metal fluoride films.

Conventional and Pulsed Liquid Injection MOCVD processes (C-MOCVD and PLI-MOCVD) have been explored as synthetic routes for the growth of BaMgF4 on Si (100) and single crystalline SrTiO3 (100) substrates. For the two applied approaches, the volatile, thermally stable β-diketonate complexes Ba(hfa)2tetraglyme and Mg(hfa)2(diglyme)2(H2O)2 have been used as single precursors (C-MOCVD) or as a solu...
