Two positions for PhD-students: Extreme ultraviolet lensless 3D imaging

As a PhD student you will develop a 3D lensless imaging system, using coherent extreme ultraviolet radiation as the light source. You will use this system to image complex lithographic nanostructures in great detail, with both high spatial resolution and chemical sensitivity.

The ability to perform high-resolution imaging without the need for lenses provides exciting possibilities in science and technology. Lensless imaging aims to do just that: visualization of objects in phase and amplitude, by numerical image reconstruction from measured diffraction patterns. Such an approach allows high-resolution microscopy using wavelengths for which good-quality optics are challenging, such as the extreme ultraviolet (EUV).

As a PhD student, your aim is to develop a 3D lensless imaging system, using a laser-driven coherent light source at EUV wavelengths (based on high-harmonic generation). You will use this new microscope to image nanostructures at high resolution, using different wavelengths to identify material composition inside such nanostructures.

You will perform this project together a team of PhD students and postdocs in the EUV Generation and Imaging group, and collaborate with researchers from the various other research groups at ARCNL. The positions are available as part of the project 3D-VIEW, funded by an ERC Consolidator Grant.
