Missions
We are looking for a postdoctoral researcher (experimentalist), who will join the Superconductivity Group at Laboratoire Albert Fert to work on Josephson and proximity devices based on cuprate superconductors, 2D materials and ferromagnets. This position is funded by the European EIC Pathfinder Open JOSEPHINE project (2024-2028), which aims to develop new superconducting electronics schemes based on high critical temperature (TC) superconductors. One aspect of the project involves manufacturing and studying Josephson devices based on d-wave cuprate superconductors, 2D materials, and ferromagnets, following earlier developments in the consortium [1-2].

Activities
The researcher will be involved in the fabrication of superconducting junctions and devices, their characterization via low-temperature ac/dc electrical transport measurements under different stimuli (electric fields, magnetic field, light). The researcher will collaborate with graduate and undergraduate students, and to some extent, will be responsible for supervising and coordinating their work
Skills
The candidate holds a PhD, and must be an experimentalist with proven experience in various of the following fields:
- Josephson physics, devices and measurements; superconducting proximity.
- Superconducting cuprates;
- ac/dc transport characterization of superconductors
- Lithography, work in clean room environment;
Personal & soft skills: Excellent team player, rigorous and enthusiastic, the candidate has a strong scientific curiosity. Self-driven and motivated, she/he criticizes experiments and faces challenges in a constructive spirit. Fluent in spoken English, she/he writes well-organized papers in English.
Work Context
The researcher will have to collaborate with other groups in Laboratoire Albert Fert as well as with other members of JOSEPHINE's consortium in Swedish, German, and Spanish institutions.
