Offer Description

The duties assigned to the recruited person will consist of:

• Preparation of optoelectronic devices based on 2D chiral halide perovskite materials prepared at MOLTECH-Anjou laboratory.
• The analysis of spin‑polarized electron transport properties in the device in order to calculate the chirality‑induced spin selectivity (CISS effect).
• The use of this spin‑filtering effect for the fabrication of spintronic devices, such as Spin‑LEDs emitting circularly polarized light (CPL).
• Promote and disseminate the obtained results.

Find device architecture in order to (i) measure the CISS effect and (ii) build Spin‑LEDs based on chiral halide perovskites and organic emitting materials (choice of electrodes, electron and hole transporting layers, and emitting layer depending on the selected perovskite).

• Characterization of the CISS effect (current–voltage measurements under external magnetic field).
• Characterization of the Spin‑LED device performances (electroluminescence, quantum efficiency).
• Involvement and participation in training internship students in direct relation with the research project.
• Dissemination, valorisation and promotion of the results (scientific papers, participation in conferences).

The MOLTECH-Anjou Laboratory (a joint CNRS-University of Angers research unit) brings together the expertise of 80 people, including nearly 50 CNRS researchers, academic researchers, engineers, and technical staff, as well as around 30 doctoral and post‑doctoral researchers. The scientific activity of the MOLTECH-Anjou Laboratory focuses on the development of molecular materials, whether organic or hybrid organic‑inorganic, supporting high‑visibility research areas such as organic electronics, stimuli‑responsive materials, nanostructuring, and materials for energy. Six research teams combine their expertise in theoretical and computational chemistry, organic and inorganic synthesis, coordination and supramolecular chemistry, physical and analytical chemistry, materials design, and photonics. Five teams are affiliated with the CNRS National Institute of Chemistry (INC), while the sixth is part of the CNRS National Institute of Physics (CIMI – ECHO – KEMTRONIX – PulSAr – VoltEdge – SAMSON).

The selected candidate will work in the frame of the ANR JCJC project ChiroSpin for the CIMI Team. This project aims to understand the chemical and structural parameters that can influence the electron's spin polarization in chiral halide perovskites, and to use this property in spintronic devices in order to improve quantum efficiency and control light and current polarization.

The candidate must hold a PhD in Physics or Chemistry‑Physics. The candidate must be motivated by research, and should have solid knowledge in physics of optoelectronic devices, a good knowledge and interest for light polarization (CD, CPL) and electric current spin polarization (CISS effect, spintronic devices). The candidate should be able to present the results of the project (a good level of English knowledge is required). Other skills such as thin film surface analysis (profilometry, AFM) and chiroptical methods will be highly appreciated.
