Superconducting Materials and Large Scale Nanostructures

Nanostructured superconductors and oxide materials understanding provide a path towards an energy sustainable world.

The Superconducting Materials and Large Scale Nanostructures (SUMAN) group has been active in the field of superconducting materials since the discovery of High Temperature superconductors, and it has widely contributed to the field of vortex pinning analysis and materials development for more than 20 years. More recently it has shifted its interests towards the chemical solution approaches to superconducting thin films and coated conductors, due to its high potential in terms of cost-effectiveness for practical applications. Moreover, the department is contributing to develop chemical processing methods to oxide nanostructures for electronics and photovoltaics. Overall, the research approach of the department is based on vast scientific and technological interests which try to combine the generation of new knowledge in several fields at effective costs for a strategic sector with one of the highest social and environmental concerns: the development of a sustainable energy paradigm.

The physical properties of the nanostructured superconductors and oxide materials studied at the SUMAN group are mainly influenced by the growth methods of the thin films, and their microstructure, which can be modified by different chemical or physical methods

Achievements

The entangled correlation between growth mechanism, its (nano)microstructure and the physical properties is at the origin of many novel phenomena and opportunities of oxide materials. At SUMAN group, we have investigated several oxide materials, mostly in the form of films, relying on chemical growth methods and defects analysis at atomic scale, for the understanding and engineering of superconducting, ferromagnetic, photovoltaic and electronic properties. Solution deposition has enable to demonstrate high temperature superconducting nanocomposite films growth with preformed nanoparticles as novel flux pinning centers. Oxygen vacancies have been detected as a very reliable defect and defect cluster to control the electronic properties of high temperature superconductors, also in resistive switching effects. High current thick HTS conductors have been grown using single-pass inkjet printing deposition.

A novel high throughput CSD method based on growth from transient liquids has demonstrated ultrahigh growth rates of YBa2Cu3O7-x films, where in-situ ultrafast XRD synchrotron experiments elucidated the growth mechanisms. A combinatorial approached based on ink jet printing deposition has started with the aim to advanced fast materials selection by machine learning. Superconducting nanowires have evidenced the highest critical current densities ever envisaged reaching theoretical depairing currents. We have placed superconducting Coated Conductors at the scene of future high energy circular accelerators for their low surface impedance properties at microwave frequencies, and are now seriously considered to protect high voltage dc grids.

In addition, chemical solution deposition has demonstrated its versatility in BiFe1-xCoxO3 ferroelectric perovskites films to tune the band gap, and in La1-xSrxMnO3 complex oxide films to engineer the oxygen migration in the novel phenomena of homogeneous volume resistive switching. Furthermore, we have continued studying other chemical methods like atomic layer deposition (ALD) for homogeneous Fe2O3 coatings of C-nanotubes, and polymer assisted deposition (PAD) for La0.92MnO3 thin films growth with dynamic magnetic and spin pumping properties, and for La2AMnO6 (A=Co, Ni) double perovskites with full cationic ordering and optimized magnetic properties.
