General information

Reference : UMR125-HERMON-003
Workplace : AUBERVILLIERS
Date of publication : Friday, June 26, 2020
Type of Contract : FTC Scientist
Contract Period : 12 months
Expected date of employment : 1 September 2020
Proportion of work : Full time
Remuneration : 2800-3700 € (w/o tax per month)
Desired level of education : PhD
Experience required : 1 to 4 years

Missions

The goal of the 1y mission is to study at the atom scale, the behavior of thin layers' stacks (metal, oxide…) as a function of the annealing temperature.
Experimenter with a PHD in material science with solid knowledge in atomic diffusion, the candidate will have to master the different aspects of Atom Probe Tomography: tips preparation by FIB-SEM, acquisition, data treatment.

Activities

In the framework of collaboration with the Institute of Physic of RWTH University in AACHEN (Germany), we propose to study the impact of the temperature applied to the stack of different nano-layers (oxide, metal) at the atomic scale. To access to the composition of the sub-nanometric scale in order to identify the phenomena occurring within these heterogeneous systems (interfaces, grains boundaries in polycrystalline layers), AtomProbe Tomography is most adapted tool. This postdoctoral work will consist in:
- Participating in the development of thin film stacks by PVD
- Defining the thermal treatments to be applied
- Operating the tip preparation by FIB-SEM according to different configurations (cross section, plan view)
- Performing the APT acquisitions
- Interpreting the data and establish the reaction scenario within the layers and at the interfaces
- Synthesizing and capitalize all the results obtained.

Skills

Knowledge in material science and reactive diffusion mechanisms
Characterization by Atom Probe Tomography
Technique of tip preparation using FIB-SEM equipment
Data analysis of APT results
Knowledge of “thin layers” (process, property) would be a plus

Work Context

This position is assigned to the SVI laboratory which is a joint unit Saint-Gobain-CNRS, located in the Saint Gobain Research Paris center in Aubervilliers (93), but the position will take place essentially (9 months) at the RWTH Physics Institute in AACHEN (Germany)
