Missions

The post-doctoral fellow will be in charge of all the team's activities concerning the characterisation of structural properties in the materials and nanostructures for nanoelectronics that are developed there. Several activities in this field are carried out in the framework of national and European research projects, or other scientific collaborations. These activities cover several types of materials, ranging from Cu and/or Ru-based metallic interconnects, to materials for source/drain junction engineering (group IV semiconductors [Si, SiGe] and new group VI ion hyperdoping solutions), vertical nanowires in Si and SiGe, and topological insulators for quantum computing. The fabrication processes studied include ion implantation, electron lithography, etching, molecular jet epitaxy and ultra-fast laser annealing heat treatments.
The post-doc will work in close collaboration with the engineers of the LAAS nanotechnology platform for the fabrication of the TEM specimens using the FIB technique and with the engineers of the Raimond Castaing characterization platform in Toulouse where he/she will perform the investigations by transmission electron microscopy.

Activities

- Structural and chemical characterization of thin semiconductor or metal layers following a nanosecond laser anneal, by several TEM-based techniques, including HREM, STEM/HAADF, STEM/EDX and Weak Beam Dark Field
- Identification of the crystalline or poly-crystalline structure of the various materials studied using high resolution TEM techniques
- Identification of the best procedures for the preparation of thin TEM lamellas
- Identification of complementary experimental techniques for the investigation of the above mentioned phenomena (Electron BackScatter Diffraction, Atom Probe Tomography, X-ray diffraction, Photoluminescence…)

Skills

- PhD in physics, materials science or nanotechnology
- Strong skills in advanced nano-characterisation by Transmission Electron Microscopy. Skills in the SEM/FIB technique will be appreciated
- Ability to fluently write and speak in English due to the frequently planned international meetings and written reporting activities as well as continuous mail and telephone exchanges within the different projects in progress
- Good team-working capacity (several interaction to occur with both the project partners as well as the engineers/technical staff working in the local laboratory)

Work Context

With a large number of permanent researchers, engineers and PhD students as well as strong interactions with industry, the LAAS-CNRS stands at the crossing between scientific research, innovation and applications. The LAAS-CNRS possesses one of the most important technological installations dedicated to research in France, with an ultra-modern cleanroom of 1600m² as well as a characterization platform (1200 m2) hosting numerous equipment for the electrical, optical, HF and chemical/bio characterization of micro and nano-systems. In particular, a SEM/FIB equipment is available at LAAS for the fabrication of thin lamellas for TEM analysis. State-of-the-art TEM equipment are available at accessible at the UMS R. Castaing characterization platform of the University of Toulouse.
The project will take place mainly in the host laboratory in Toulouse, but the post-doc researcher will work in a very stimulating research environment in the framework of numerous academic and industrial collaborations at French and European level.

Additional Information
