PhD in High-Harmonic Generation and Spectroscopy of Liquids and Few-layer Solids Advanced Research Center for Nanolithography in Netherlands

The Advanced Research Center for Nanolithography (ARCNL) in Amsterdam is offering a fully funded PhD position in the Short Wavelength Light Sources for EUV Metrology group, led by Dr. Angana Mondal. This research opportunity is at the intersection of fundamental physics and advanced spectroscopy, focusing on high-harmonic generation (HHG) techniques to study ultrafast dynamics in liquids and few-layer solids. The project aims to develop designable coherent sources of extreme ultraviolet (EUV) or soft X-rays, with applications in imaging and metrology for semiconductor materials and interfaces.

As a PhD candidate, you will design and build beamlines for HHG sources, perform experiments with ultrafast laser systems, develop spectroscopic and interferometric methods, and analyze large datasets to uncover mechanisms governing light emission and structural dynamics at femtosecond to attosecond timescales. The research group explores novel materials such as liquids and 2D solids to overcome the limitations of traditional HHG sources, leveraging the intermediate properties of condensed, disordered systems to combine high photon energies and brilliance.

Applicants should have or be close to completing a Master's degree in Physics, Physical Chemistry, Materials Science, or a related field, and must meet Dutch university requirements for PhD enrollment. A strong interest in nonlinear optics, materials science, and chemistry is essential, along with proficiency in English. Experience with femtosecond lasers, programming (Python, MATLAB), vacuum systems, EUV/X-ray instrumentation, and knowledge of high-harmonic generation or laser-matter interaction are advantageous.

The position is fully funded for four years, with a starting gross salary of €3,115 per month and comprehensive employment benefits, including housing and visa support for international students. The research environment at ARCNL is highly collaborative, with close ties to the semiconductor industry and a focus on scientific excellence. The successful candidate will contribute to publications in leading journals and present results at international conferences.
