Description of the thesis topic
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 by synthetized 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
