Title: Thermoelectric detector based on superconductor-ferromagnet heterostructures (SUPERTED)
Funding Agency: European Commission
local PI: Sebastian Bergeret
Summary:
In this project, we propose to study a new type of radiation sensor that overcomes limitation state-of-the-art superconducting sensors.
The proposed detector is based on the thermoelectric conversion of the radiation signal to electrically measurable one.
This approach is based on the newly found giant thermoelectric effect taking place in superconductor/ferromagnet heterostructures.
Utilising this effect, the sensor pixels can be self-powered by the measured radiation, and therefore extra bias lines are not needed.
Within the project, we aim to establish a proof of concept of this device by
1) fabricating such detector elements,
2) characterising single-pixels of thermoelectric detectors for X-ray and THz imaging via approaches that are scalable to large arrays.
In the project participate groups from Centro de Físca de Materiales (CSIC-UPV), University of Jyväskylä (Finland), The National Center for Scientific Research (CNRS, France), The National Research Council (CNR, Italy) and the company BihurCrystal (san Sebastian).
Title: Spintronics and Spin-orbitronics in hybrid nanostrctures: From classical to quantum technologies. (PID2020-114252GB-I00)

Summary:
SPIRIT is a project that aims at combining superconductors, materials with spin-orbit interaction, and magnetic insulators into a new generation of spintronics devices which exploit heavily the coupling between the charge and spin currents as well as quantum effects to obtain unique spin-dependent properties at the mesoscale -- at the crossroads between classical and quantum technologies. SPIRIT brings together both theory and experiment to create a stimulating collaborative environment, where advanced electronic transport theory in mesoscopic systems and experimental activities in both manufacturing and characterization come together to create and describe new material systems and study new physics at interfaces. Two groups from the Centro de Física de Materiales CFM in San Sebastián will carry out the project: the Mesoscopic Physics Group, in charge of the theory part, and the Surface Magnetism and Superconductivity Group within the Nanophysics Lab, in charge of the experimental part.
