Researcher (fixed Term) - Development of the terahertz atom probe for analysis of biological materials (M/F)

Job Description

Missions

In the framework of the Tera Seed project, funded by the Normandy Region, the work involves developing new procedures for preparing biological samples for THz atomic probe analysis. The use of new metal matrices for encapsulating biological materials will be explored, as well as new techniques for depositing metal coatings.

Activity

Atom Probe Tomography (APT) is an advanced characterization technique with very high spatial resolution that enables three-dimensional analytical imaging of materials at the atomic scale. The use of THz sources improves the quality of atom-probe results for metallic materials. For non-metallic materials, the recruited researcher will implement new sample preparation techniques, such as the encapsulation of biological materials in metallic matrices (Au, Cu, Ag) containing nanopores. The metallic matrix will allow for better amplification of the THz field and thus improved analysis of biomaterials. In addition, cryogenic preparation techniques will be implemented to shape the biological samples and investigate how to coat them with a thin metal layer, which will also amplify the THz field. All ÀPT samples will be shaped into tips using FIB-SEM.

- Preparation of biological samples for atomic probe tomography
