Correlative atom probe tomography and analytical electron tomography: A pathtowards the ultimate 3D characterization with sub-nanometric resolution.

Research field : Materials and applications / Engineering scienceAtom probe tomography (APT) and analytical electron tomography (AET) are excellent tools for 3D characterization of nanomaterials. However, there is a great interest in combining results obtained with these two techniques, as they are complementary in many ways: for example, AET provides 3D analysis of larger fields of views with higher spatial fidelity than APT, but has more limited spatial resolution and composition sensitivity.In this project, we will develop a Python-based framework for 3D data fusion of APT and AET signals. Sampling schemes, denoising approaches and registration methods will be implemented in order to tackle the following tasks:

Correction of distortions and local atom mixing in the reconstructed APT volumes, by using the AETvolumes as prior knowledge.

Combination of large field-of-view AET volumes with APT sub-volumes (small precipitates resolved, andlow concentration dopants detected).

Use of APT (fully quantitative) reconstruction to validate the quantification methods currently developedby the AET community.

Comprehensive characterization of selected materials: model alloy of a reactor pressure vessel (RPV) containing nanoprecipitates to validate the approach; and towards the end of the project, nanodevices for semiconductor industry.
