General description

CRHEA-CNRS is involved in the growth of wide-bandgap semiconductors (GaN and ZnO) by several techniques, including MBE and MOVPE. The main growth activity is supported by structural (high resolution X-ray Diffraction, scanning and transmission electron microscopy, atomic force microscopy and scanning tunneling microscopy), optical (photoluminescence, reflectivity, electro-optic measurements) and electrical characterization (C-V, Hall, resistivity) techniques. Besides, our clean room allows fabricating test devices (GaN-based LEDs and laser diodes are two examples) that enable assessing the quality of the obtained heterostructures and the fabrication of more complex heterostructures, as polaritons lasers. Indeed, in such structures we have recently observed room-temperature polariton Bose-Einstein condensation, which should allow the development of new coherent sources, similar to lasers but with much smaller “lasing thresholds”.


 Please note – In order to comply with CNRS salary policy, CRHEA will only be able to accept postdocs who have defended their PhD less than two years before the Call. The duration will be ascertained with reference to the date when the final employment contract with CRHEA is signed.

As per COFUND guidelines, fellowship programmes will be based on individual-driven mobility, i.e., researchers will be able to freely choose a research topic fitting their individual needs.

The subject of the research project is expected to contribute to European competitiveness and to be in the general field of Photonics and/or its applications. Within these limitations, applicants can freely choose both their research topic and their host organisation, in the spirit of the ‘European Charter for Researchers’.
