Post-doctoral position open at Photonique-LAAS-CNRS et ISAE

Duration : 18 months
LAAS-CNRS : LAAS-CNRS, Toulouse, France, co-hosted with ISAE

Contact : Olivier GAUTHIER-LAFAYE
The ATRIUM project aims to demonstrate the potential of technological breakthrough that is the emergence of 3D imaging systems focal planes for embedded systems, especially UAV systems that can benefit from this technology for both their autonomy (navigation, landing aid, obstacle detection), but also as a primary mission (3D mapping, 3D site monitoring, emergency aid visibility degraded) or measures of components (materials, gas or aerosols) with multispectral systems. In this context, the LAAS-CNRS, develops nanostructured filters based on grating mode resonant filters (GMRF). Such filters can be integrated into these systems to allow separation of the laser signal of atmospheric background. These optical filters enable new generation of filtering functions inaccessible to conventional optical interference filters, particularly in terms of spectral bandwidth. Their implementation is based on simple multilayers, ensuring greater reliability, simpler producing methods compatible with microelectronic processing, and enabling technology transfer for mass-manufacturing.
The post-doctoral position will mainly focus on the key issue of nanofabrication, aiming at the realization of large-area components (the objective is the realization of 2'' diameter components commensurable with conventional optical systems). To ensure this objective, a technique of next generation lithography is proposed: the nano-imprint lithography. The challenge will be to integrate this step in a full fabrication process, making it compatible with more generic processes such as lithography, etching, deposition and characterization. This process development will enable the candidate to develop a broad vision of technological issues at the nanoscale and to propose an attractive solution for GMRF manufacturing.
Finally, the post-doctoral fellow will collaborate with the ISAE team to plan and configure the integration of these filters in LIDAR systems developed within the project.
Profile: PhD or postdoc with strong experience in microtechnology and clean-room processing. Nanoimprint technology experience is a plus. Ideally, the candidate will present basic training or experience in optics / photonics.


Nano-material scientist 

Location: LAAS-CNRS, Toulouse, FRANCE

Duration: 18 months

LAAS-CNRS seeks for a self-motivated post-doctoral researcher to take in charge a French-US research project aimed at developing advanced nano-material for energy production applications.

The main goal is to explore how the interface chemistry of nanomaterials affects their thermal properties. This position will involve the synthesis of nanoscale thermite materials (e.g., Al/CuO nanolayers) including potential physico-chemical modifications of their interfaces. The candidate will interact with a larger group effort exploring advanced thin films and nanomaterials for energy production applications, with a particular emphasis on controlling the physical structure and interface chemistry of Al/CuO nanolaminates to develop a better understanding of the fundamental structure-property relationships  of such materials. The collaborative environment requires a candidate who has the ability to work as part of a team with scientists coming from different disciplines and to learn topics outside his area of expertise. The position will involve a combination of nano fabrication (RIE, photolithography, PVD), advanced characterization (HR-TEM, XPS, DRX) as well thermal and electrical analysis to characterize accurately the energetic capabilities.

The candidate will be required to work temporary in clean room facilities and to follow safe work procedures, as well as to handle chemical waste properly and keep a clean, well-organized work environment.

Required Education and Experience:

Must be a recent PhD graduate (within the last three years).

The ideal candidate for this position should have a strong background in the following areas: (1) nanomaterial synthesis and manipulation; (2) physico-chemical modificaions of surfaces (e.g., nanocrystals, nanowires, thin films); and (3) nanoscale characterizing  nanomaterials and their surfaces. Although general expertise in nanotechnologies, chemical engineering and manipulation will be considered.


Preferred Qualifications Ph.D. in materials science & engineering, physics, mechanical/electrical engineering or related fields.
