Postdoc: Light-induced damage at the atomic scale using in situ TEM
Work Activities
What are the atomic-scale processes behind light-induced damage?
Light-induced damage presents a challenge in applications of high-power lasers, including semiconductor device manufacturing. For the prevention of damage, it is particularly interesting to identify the changes to materials before any degradation of performance is discernible. The emergence of damage is often attributed to the creation of defects or the enhanced interaction of defect sites with external stimuli. Which defects are crucial in damage processes and how different defect types respond to laser pulses, however, remains unresolved at the atomic scale. In this project, you will address these questions using high-resolution transmission electron microscopy (TEM) with in-situ laser exposure. You will shed light on the atomic-scale mechanisms of defect generation and damage below the threshold for macroscopic changes, and connect material properties to the light-induced damage patterns of nanometer thick layers.
Your role as postdoc
You will perform your research in a collaboration between the Light-Matter Interaction group and the Materials & Surface Science for EUVL group at ARCNL, the Hybrid Nanosystems group at AMOLF, and the semiconductor equipment manufacturing company ASML. With guidance from these project partners, you will develop a research plan to resolve the atomic-scale details of light-induced modifications to thin films in the context of nanolithography and optical metrology. You will operate a state-of-the-art aberration corrected TEM with unique light incoupling and ultrafast time-resolution capabilities. You will have access to thin-film preparation and surface characterization facilities at ARCNL and AMOLF to fabricate thin layers and characterize their composition and structure. With the help of experts in the respective methods, you will grow layers for the TEM experiments and have the option to pre- and post-characterize them with several techniques such as atomic-force microscopy (AFM), optical microscopy, scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and Raman spectroscopy.
Qualifications
- You have a PhD in Physics, Physical Chemistry, or Materials Science and hands-on experience with transmission electron microscopy.
- You are independent and have good project management skills.
- Good verbal and written communication skills (in English) are required.
- A background in light-matter interaction, laser spectroscopy, thin-film growth, or surface science is considered an advantage for the project.

Phd - student: Ultrafast photoacoustics for semiconductor metrology
Work Activities
Background
In semiconductor device manufacturing, optical metrology tools are used determine the position of a Si wafer by measuring light, scattered from so-called alignment markers. When these markers become covered in materials that are optically opaque, measuring scattered light becomes a challenge. A possible solution to that challenge is the use of photoacoustics. There, a pump pulse rapidly heats up an absorbing material, launching a strain wave in the process. That strain wave propagates to and reflects off the marker, creating a strain-wave copy. At the surface, light measures this strain wave copy of the marker allowing us to indirectly observe the hidden markers. The process works, but signal strength must be improved to make real-world applications possible.
Project goal
In this project you will work towards improving the signal-to-noise ratio in photoacoustics by using hitherto underexplored techniques, aimed at both increasing signal strength and decreasing noise. This can for example be done by optimizing the optical wavelengths used for the generation and detection of the strain waves and by using optical transitions to enhance detection sensitivity.
After you join our group, your goal is to design and execute photoacoustics experiments aimed to generate and detect strain waves with femtosecond laser pulses, and to improve the detection signal-to-noise ratio. You will learn to work with high-power femtosecond lasers to perform ultrafast time-resolved reflection and diffraction experiment for the generation and detection of strain waves. You will get acquainted with nonlinear optics, perform experiments on relevant materials, and learn how to analyze your data. The research will be done in close collaboration with the ASML research department.
Qualifications
You have (or soon will have) a MSc degree in physics, chemistry, or materials science or equivalent, to satisfy the Dutch university requirement to enter a PhD program. Previous experience with femtosecond lasers is not required but it would be a plus. An interest in non-linear optics, materials science and chemistry is needed, as are critical thinking, and creative problem-solving skills. Good verbal and written communication skills in English are required.

Hydrodynamics of droplet deformation & fragmentation for EUV lithography
Work Activities
This postdoctoral position lies at the interface between fundamental physics and industrial application. It is part of a fully funded Consolidator Grant from the European Research Council titled “Next-Generation Light Source: Driving plasmas to power tomorrow’s nanolithography (MOORELIGHT)”.
Background
Advanced semiconductor devices are produced using extreme ultraviolet (EUV) light at just 13.5nm wavelength. The recent revolutionary introduction of EUV lithography (EUVL) was the culmination of several decades of collaborative work between industry and science – a Project Apollo of the digital age. EUVL is powered by light that is produced in the interaction of high-energy CO2-gas laser pulses with molten tin microdroplets. The use of such lasers leads to low overall efficiency in converting electrical power to useful EUV light. Replacing gas lasers with much more efficient solid-state lasers may significantly improve efficiency, as well as output power. It is currently however unclear what laser wavelength, and what plasma ‘recipe’ should be used. This is because we lack understanding of the underlying complex physics. The goal of project MOORELIGHT is to deliver the missing insight.
Project goal
The EUV-emitting laser-produced plasmas are generated from tin targets carefully shaped (i.e, hydrodynamically deformed) by a series of laser “pre-pulses”. The ability to shape and control these tin targets is critical for the efficient generation of EUV light in current and future light sources. Achieving such a precise control requires a detailed understanding of the underlying hydrodynamic processes.
You will join an interdisciplinary team of several PhD students and postdocs with the objective of understanding the fluid mechanics underlying target formation, ranging from the (in)compressible flow initiated by impact to the various instabilities that lead to the fragmentation of thin tin sheets. You will be responsible for the design, setup, execution, analysis, and interpretation of experiments and simulations. As part of your work, you will closely collaborate with researchers in the Jalaal group at University of Amsterdam.
Qualifications
You have (or soon will have) a PhD related to the field of fluid mechanics. Programming skills (Python and/or C) are required. Good verbal and written communication skills (in English) are required.
Work environment

ARCNL is located at the Amsterdam Science Park, The Netherlands, and has a size of approximately 100 scientists and support staff. See also www.arcnl.nl.
The research activities of the EUV Plasma Processes group aim at the atomic- and molecular-level understanding of the fundamental dynamics in the operation of contemporary and future plasma-based sources of extreme-ultraviolet (EUV) light for nanolithography.
Working conditions
The position is intended as full-time (40 hours / week, 12 months / year) appointment in the service of the Netherlands Foundation of Scientific Research Institutes (NWO-I) for the duration of up to 3 years, with a salary in scale 10 (CAO-OI) and a range of employment benefits.

PhD position: Applying high efficiency Si PV principles to halide perovskites
Work Activities
As the perovskite layer quality increases, the surfaces and interfaces begin to dominate the remaining efficiency loss. The Si PV industry has developed standardized tools and protocols for rapidly screening new passivation and contact materials and quantifying their quality. There is so far no comparable standardization in halide perovskite PV which hampers further efficiency improvements. Furthermore, doping and impurity gettering in Si are highly controlled using drive-in from external surface layers (e.g. borosilicate or phosphosilicate glass) followed by RTA or furnace annealing, while there is no comparable procedure for controlling doping density or gettering defects in halide perovskite PV. Even measuring doping density (or free carrier concentration) is difficult in halide perovskites, while this is a standard rapid measurement in crystalline Si PV and a critical parameter to optimize for peak performance.
The goal of this project is translate concepts developed in high-efficiency Si PV R&D to halide perovskites. There are both fundamental and more applied aspects to the project. The fundamental Research questions are:
Can we develop a comparable suite of standard characterization techniques for halide perovskites as exist in high-efficiency Si PV? These include for example measuring surface/interface recombination velocity, bulk vs. surface lifetime, J0, implied Voc, doping density/carrier concentration.
Can we develop strategies to reliably dope halide perovskites, especially selectively at the contacts? These could include more traditional doping but also remote doping (e.g. in analogy to doped poly-Si tunnel contacts or doped a-Si heterojunction contacts).
Research goals:
- Develop fast screening method for passivating contacts analogous to the Sinton tester used in Si PV research and development. Use this to find improved carrier selective contacts and passivation layers.
- Develop surface/interfacial layers to controllably dope/passivate halide perovskites selectively at the contact or apply remote doping analogous to poly-Si passivated contacts.
- Implement optical annealing with pulsed lasers to provide highly controllable interfacial processing (annealing, doping, passivation, recrystallization) with simultaneous tracking and feedback via PL and absorption signal, taking advantage of developments in machine learning.
Embedding
The project is part of a large national initiative, SolarLab, aimed at coordinating all academic solar research in the Netherlands and supporting the Dutch solar photovoltaic industry. For more information, visit solarlab-nl.org.
