The PhD student will develop new methods for high-resolution lensless microscopy with coherent soft-X-ray and extreme ultraviolet radiation, produced using a table-top laser-driven high-harmonic generation source.
You will work on the visualization of complex 3D nanostructures, and develop imaging and metrology tools that may become relevant for future semiconductor technology.
The ability to perform high-resolution imaging without the need for lenses provides exciting possibilities in science and technology. With lensless imaging, visualizing objects in phase and amplitude is performed by numerical reconstruction of an image from coherent diffraction patterns, which leads to completely new ways of optical imaging. This type of imaging enables the use of sources in wavelength ranges where high-quality imaging optics are challenging, such as the extreme-ultraviolet and soft-X-ray ranges.
As a PhD student, you will work with (and further develop) a coherent soft-X-ray source based on high-harmonic generation with an intense ultrafast laser system. You will use this source for the development of new 3D nano-imaging technology, and investigate methods for the detection and characterization of sub-wavelength nanostructures, using lensless imaging approaches such as coherent diffractive imaging methods and ptychography.
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. This position is available as part of the LINX consortium, a national NWO-TTW-funded collaborative project involving research groups from ARCNL, Delft, Utrecht, Twente and Eindhoven, as well as several companies.
