Many of the current challenges in the rational and efficient use of the energy extend to whole classes of electronic devices, particularly in the mobile sector. For these, energy harvesting, energy savings and energy conversion are key concepts that should be exploited. Contemporary research aims at making devicesmore powerful while consuming less energy, and this at affordable production costs.

The present project will address those challenges by designing materials in which various energy reduction schemes can be implemented. We envision cutting edge nanotechnology, oxide and superconducting spintronics technologies in the SPICOLOST framework triggering the connection and cooperation between international labs and technology companies. The project will foster the sharing of knowledge, cross-linked work and innovation, particularly between Europe and overseas.

The SPICOLOST project’s technical work will follow two main parallel approaches:

  1. exploiting suitable heterostructures for high-efficiency conversion of thermal- into electrical energy, taking the advantage of harvesting, in the so-called thermoelectric thermopile device based on the Seebeck and Spin-Seebeck Effects;
  2. producing multicomponent nanostructured materials for magneto-electronic and superconducting devices, capable of fast signal processing, and minimizing the energy dissipation by proper control of the magnetic switching, thus consuming less energy.

We anticipate providing advances in experimental fabrication processes, improvements in the control of interface properties of hybrid heterostructures. Further, as suitable theoretical frameworks comprehensively describe the synergies between superconducting- and spintronic techniques we look forward to novel discoveries that will be made possible.
