"Growth and characterization of materials and devices of reduced dimensionality: thin films of superconductors and other advanced materials, micro-patterned and/or nano-structured systems"


-1.1. Growth of thin films of metallic and complex materials

Growth of thin films of superconductors and other materials (semiconductors, etc.) as well as their structure characterization after causing in them micropatterning (microbridges, etc.) and/or nanostructuring (gating with ionic liquids and/or nanomasks, use of nanostructured substrates, etc.). In connection with this, the LBTS Research Group is a partner of the European COST network NanoSC for the research in nanostructured superconductors.

-1.2. Development of superconducting devices

Development of superconducting devices or components. Among them:

  • Inductive superconducting fault current limiters. The LBTS Research Group has produced various patents on this type of limiters, and several functional prototypes.
  • Superconducting fault current limiters of size suitable for integration into electronic circuits (microlimiters). Superconducting thin films are grown with ad hoc patterned microbridges to produce resistive current limiters.
  • Nanostructured superconducting components: growth of superconductors with nanostructuration induced by other materials in contact with them (gating with ionic liquids and/or nanomasks, films with nanostructured substrates, systems with vortex pinning and matching).

-1.3. Growth of alloys composed of metals and superconducting pnictides

It is addressed the growth of alloys of aluminium and superconducting pnictides based on iron, as a path to develop new types of superconducting wires and other morphologies (using extrusion).

-1.4. Development of devices for microfluidics and nanofiltration

Development, by employing our infrastructure for thin film growth and lithography, of microfluidic devices (lab-on-a-chip, etc.) for the detection of nanoparticles carried by fluids of interest (clinical and environmental applications).
