The post-doc position is open in the frame of the “IPPON” project (“Incoherent light and Phonon management in micro-nanopatterned materials for efficient depollution and artificial PhOtosyNthesis”), funded by the Lyon-Saint-Etienne IDEX “Scientific Breakthrough” program. It is an ambitious project including specialists in Physics, Chemistry and Engineering. The post-doc will specifically take part in the structural and optical characterization of the materials and photonic structures to be developed, and will contribute to their synthesis and to the modelling of their properties.

In our contemporary society, one of the most urgent challenges is the need to reduce CO2 emissions and to live in a clean environment, making it crucial to develop novel concepts for efficient depollution and energy conversion and storage in a variety of forms, among which chemicals. Photocatalysis is the key approach to reach these objectives, based on the use of sunlight or inexpensive artificial light sources. Still, the efficiency of these reactions would substantially benefit from the unprecedented potential of nanophotonics to trap and confine light and of nanophononics to control temperatures locally.


The objective of this project is to develop novel concepts based using advanced micro and nanostructured media enabling both incoherent light confinement and thermal trapping. To achieve this, we will develop a complete methodology based on theoretical predictions, multi-domain and multi-scale modelling, chemical synthesis and micro-nanopatterning of functional materials, advanced experiments in optics, phonon dynamics and photochemistry, by combining the skills of scientists from 4 laboratories in Lyon and Saint-Etienne: INL, Lab.HC, ILM and IRCELYON, specialists in physics, chemistry and engineering, from CNRS, ECL, INSA Lyon, UCBL and UJM. Several post-docs and a PhD student are recruited in the frame of this project, working together with a view to achieve important breakthrough including:
-The design and fabrication of micro-nanostructured media dedicated to photocatalysis, using original and scalable approaches.
-The demonstration of novel photocatalysis regimes, with enhanced yield, due to local thermal trapping in illuminated nanostructured media.
-The demonstration of efficient depollution and artificial photosynthesis.

These demonstrations will be based on demonstrators including structures like photonic crystals, acting as an optical backbone, covered with a photocatalytic medium


The main objectives of this post-doc will be to contribute to the measurement and control of the properties of the active materials. He/she will perform experimental studies involving X-ray diffraction, electron microscopy, optical spectroscopy. He/she could also contribute to the deposition of the targeted materials, and to the modelling of the properties of the materials and photonic structures to be developed. The post-doc will benefit from the know-how and equipment available at INL (structural and optical characterization, electromagnetic simulation, nanofabrication) and at Lab.HC (modelling, optical spectroscopy).

Candidates are expected to have a strong background in functional materials, and their structural and optical properties. He/she should have a substantial know-how in at least one of the following topics: optical characterization (spectroscopy, micro-reflectance, etc), X-ray diffraction, electron microscopy, electromagnetic simulation (FDTD, RCWA), photonic crystals.
