Forschungsförderungsprojekt
The development of low cost technologies for mass production of nano-structured materials based on chemical solution processing is the overall objective of the project. Novel nano-structuring methodologies are envisaged for the growth of epitaxial nanocomposite films and coated conductors having high performances. The originality of the project is to combine two fast-growth rate chemical processing techniques (Metal-organic decomposition and Hybrid liquid phase epitaxy) for growing epitaxial REBa2Cu3O7 High-temperature superconductor films with bottom-up nano-structuring strategies. The purpose is to achieve an artificial network of nano-defects which will immobilize the superconducting vortices and hence high critical currents with low magnetic field dependences will be achieved in films and coated conductors with high thicknesses. A first general strategy for nano-structuring the superconducting layers is based on the generation of coherent nano-structures randomly distributed, such as nano-dots. The second strategy is to engineer nanostructures originated at the substrate interface, either based on strain-induced self-assembling principles or on polymer track-etched cylindrical nanopores generated by ion bombardment. The final technological goal is to develop nanostructured coated conductors of 1 m length having a total critical current of 400 A in a 1 cm width tape with a reduction of thickness and magnetic field dependence by a factor of 3 compared to the present state of the art. This achievement will represent a real scientific breakthrough which will quickly push coated conductors toward applications in fields such as electric power technology.
