PhD position in quantitative analysis of imaging and analytical techniques in scanning transmission electron microscopy

The EMAT research group at the department of Physics (University of Antwerp) and the STEM group at the department of Materials (University of Oxford) are seeking to fill a PhD position under the supervision of Prof Sandra Van Aert (University of Antwerp) and Prof Peter D Nellist (University of Oxford). The project goal is to develop a multivariate statistical framework to simultaneously analyse imaging and analytical data in scanning transmission electron microscopy.

The main goal of this project is to realize a major breakthrough in the quantitative analysis of imaging and analytical techniques in scanning transmission electron microscopy (STEM). Therefore, we will exploit the physics-based description of the fundamental processes of electron scattering and combine this with a thorough multivariate statistical analysis of the recorded signals. In this manner, we will be able to identify the chemical nature of all individual atoms in three dimensions. So far, imaging and analytical signals have mostly been analysed separately in STEM. Although analytical techniques are in principle well suited because of their elemental specificity, they have a much lower signal to noise ratio as compared to imaging techniques. We foresee that our multivariate method, in which new physics-based models are incorporated to describe the electron-object interaction, enables us to achieve element-specific atom counting at a local scale and to determine even the ordering of the atoms along the viewing direction. Furthermore, our approach will be optimized to reach high elemental measurement precision for a minimum incoming electron dose. This novel dose-efficient quantitative methodology will clearly usher electron microscopy in a new era of 3D element-specific metrology at the atomic scale and allow characterisation of beam-sensitive materials. This will exactly provide the input needed to understand the unique link between a material’s structure and its properties in both materials and in life sciences.

Research group

EMAT is one of the leading electron microscopy centers in the world and has a vast expertise in both fundamental and applied electron microscopy. EMAT has several state of the art electron microscopes including two aberration corrected, high end FEI-Titan instruments, a dual beam FIB, an environmental SEM,... More about us at our webpage .
