Research group imec - Vision lab of the Department of Physics in the Faculty of Science is looking for a full-time (100%) PhD student in the field of 3D tomography of nano-samples.

Position

Imec-Vision Lab at the University of Antwerp (http://visielab.uantwerpen.be/  ) has an open position for a PhD researcher to strengthen our tomography research team with, for this position, a particular emphasis on Atom Probe Tomography (APT). Tomography is an image reconstruction technique that leans strongly on large-scale numerical mathematics and computational science. It has a wide range of applications in medicine (CT-scans), industry (nondestructive testing) and science (3D imaging of nanomaterials).

The Vision Lab is a research group of the physics department at the University of Antwerp. The Vision Lab has unique expertise in the development of algorithms for reconstruction, processing and analysis of tomographic imaging data. Application domains are x-ray computed tomography (CT), MRI and electron tomography. The working environment is strongly interdisciplinary, combining techniques and insights from physics, mathematics, engineering, and computer science. The Vision Lab has a broad range of national and international collaborations with both academic and industrial partners. Recent publications on tomography can be found on http://visielab.uantwerpen.be/research/tomography .

APT is a technique used to analyze the composition and structure of materials at the atomic scale. It uses a focused laser beam to selectively ionize atoms from a sample, which are then directed towards a detector for analysis. APT allows for three-dimensional imaging of materials, with sub-nanometer resolution. It is particularly useful for studying small features or regions within a material, such as interfaces or defects. The technique can be used to study a wide range of materials, including metals, ceramics, and semiconductors. APT can provide information on the location, composition, and chemical bonding of atoms within a material. It is a powerful tool for research in materials science and engineering, as well as in the development of new materials and technologies.

An important challenge in APT is the 3D reconstruction of a nanosample from measured data. In your PhD trajectory, you will develop a radically new method for the 3D atomic resolution reconstruction of atom probe data. The technique will be dedicated to the analysis of semiconductor samples in close collaboration with imec (https://www.imec-int.com/en/home ) where atomic scale analysis of advanced semiconductor devices is pursued with Atom probe tomography.
