Missions

The position involves developing a new type of spin injector based on chiral organic-inorganic hybrid perovskites (OIHP) for spin-optoelectronic applications. Thanks to the chirality-induced spin selectivity (CISS) effect, electrons (or holes) passing through the chiral OIHP layer can generate strongly spin-polarized carriers.

Activities

- Manufacture spin-optoelectronic devices incorporating a spin injector based on the OIHP layer.
- Perform transport measurements at cryogenic temperatures to study I-V characteristics.
- Perform preliminary characterizations of electroluminescence.

Skills

- Essential proficiency in English (written and spoken) – Level C1 (Common European Framework of Reference for Languages) and French (spoken) – Level B1.
- Proficiency in UV lithography and electron beam lithography processes for the manufacture of micro- and nanoscale devices.
- Experience in transport measurements at cryogenic temperatures (10–300 K).
- Solid background in condensed matter physics.
- Strong writing skills (information notes, summary documents, etc.);
- Ability to work in a team and in a multicultural environment.

Work Context

The Institute Jean Lamour (IJL) is a joint research unit of CNRS and Université de Lorraine.
Focused on materials and processes science and engineering, it covers: materials, metallurgy, plasmas, surfaces, nanomaterials and electronics.
By 2025, IJL has 259 permanent staff (34 researchers, 133 teacher-researchers, 92 IT-BIATSS) and 374 non-permanent staff (136 doctoral students, 48 post-doctoral students / contractual researchers and more than 190 trainees), from some sixty different nationalities.
Partnerships exist with 150 companies and our research groups collaborate with more than 60 countries throughout the world.
Its exceptional instrumental platforms are spread over 4 sites ; the main one is located on Artem campus in Nancy.
The work will be carried out within the Nanomaterials for Optoelectronics team on the ANR-DFG ChiralSpinLaser project. The candidate will work at the IJL laboratory (UMR 7198) on the ARTEM campus in Nancy. Travel within Europe is to be expected.
Team 104 “Nanomaterials for Optoelectronics” (https://NanoOptoSpin. ijl.cnrs.fr) of the IJL's Physics of Matter and Materials (P2M) department is developing fundamental and applied research based on its expertise in the field of semiconductor nanomaterials to study optical and magnetic properties through detailed structural, optoelectronic, and magneto-transport characterizations.
The candidate will work full-time as a postdoctoral researcher on the ChiralSpinLaser project, which aims to explore a new type of spin injector based on chiral organic-inorganic hybrid perovskites (OIHP).

The position is located in a sector under the protection of scientific and technical potential (PPST), and therefore requires, in accordance with the regulations, that your arrival is authorized by the competent authority of the MESR.

Constraints and risks

Use of chemical solvents in lithography processes (photosensitive resin, developer, acetone, isopropanol, etc.).
