Offer Description The research work will take place at GEMaC ( https://www.gemac.uvsq.fr ) in Versailles, France. The GEMaC is a joint unit of the CNRS and the Université de Versailles Saint-Quentin-en-Yvelines, member of the Université Paris-Saclay.
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.
In recent years, halide perovskites have demonstrated exceptional optoelectronic properties. This new class of semiconductor materials has proved an extraordinary potential for the production of low-cost solar cells and light-emitting devices. Perovskite solar cells have made lightning progress, and now boast efficiencies over 26%, on par with the best silicon-based solar cells. This success leads to significant research effort to understand the physical origins of their performance. Halide perovskites are also promising for spintronic applications. They present a strong spin-orbit coupling, a relatively long spin relaxation times, and an optical accessibly for spin generation and detection.
The objective of the PhD is to explore the exciton and spin properties of halide perovskites. The samples will be synthesized in collaboration with LuMIn and ISMO laboratory, from University Paris-Saclay, in the context of the ANR project HAPERO. The candidate will study high quality perovskite materials, obtained by vacuum growth, and controlled in-situ with extremely sensitive characterization techniques.
The candidate will conduct experiments based on optical microscopy and spectroscopy. The experimental set-up includes a confocal microscope operating at cryogenic temperature (4K-300K), a superconducting magnet for application of magnetic field (9T).
The candidate should have a master degree or equivalent, with a strong background in solid-state physics and optics. The candidate should have a strong taste for experimental research. Good communication skills in English are required.
