PhD student: Laser-induced damage
The Institute of Physics (IoP ) of the University of Amsterdam and the Advanced Research Center for Nanolithography (ARCNL) have an opening for a fully funded PhD position.
Materials exposed to light inevitably suffer from optical damage when the light fluence keeps increasing. When using lasers as light sources, damage can take different forms, ranging from a reasonably gentle separation of layers of different materials (delamination), to violent and explosive removal of material, crater formation and even the creation of a plasma. We study these processes on time scales ranging from femtoseconds to seconds. We are seeking a PhD candidate who is interested in interdisciplinary research into the mechanisms behind light-induced damage in materials used in nanolithography.
What are you going to do
In this project, a collaboration between the Light-Matter Interaction group and the Materials & Surface Science for EUVL group, you will study the fundamental physics behind light-induced damage within the context of optical metrology in nanolithography. You will learn to work with high power (tunable) femtosecond laser systems, and acquire a deep understanding of light-matter interaction at high optical fluences, and of the light-induced changes in material properties. You will learn techniques to fabricate nanolayers and nanostructures using nanolithography, and to study pristine and damaged structures with techniques such as X-ray photoelectron spectroscopy (XPS), scanning-electron microscopy (SEM), atomic-force microscopy (AFM) and others. Part of your project is to use your experimental results and the knowledge gained into (numerical) models that may help predict and mitigate optical damage.
About the group
The University of Amsterdam is the Netherlands’ largest university, offering the widest range of academic programmes. At the UvA, 30,000 students, 6,000 staff members and 3,000 PhD candidates study and work in a diverse range of fields, connected by a culture of curiosity.
The Faculty of Science has a student body of around 8,000, as well as 1,800 members of staff working in education, research or support services. Researchers and students at the Faculty of Science are fascinated by every aspect of how the world works, be it elementary particles, the birth of the universe or the functioning of the brain.
The mission of the Institute of Physics (IoP) is to carry out excellent research in the field of experimental and theoretical physics, to provide inspiring teaching within the physics and other curricula and to transfer our knowledge of and enthusiasm for physics to society. The IoP has over 50 faculty and 180 researchers in total. The combination with the NWO Institutes at Amsterdam Science Park constitutes the largest physics hub in the Netherlands and is an international centre of excellence.
The Advanced Research Centre for Nanolithography (ARCNL) focuses on the fundamental physics and chemistry involved in current and future key technologies in nanolithography, primarily for the semiconductor industry. ARCNL is a public-private partnership between the Dutch Research Council (NWO), the University of Amsterdam (UvA), the VU University Amsterdam (VU) and the semiconductor equipment manufacturer ASML. ARCNL is located at the Science Park Amsterdam, The Netherlands, and is a thriving research community of approximately 100 scientists and support staff. See also www.arcnl.nl.
In the Light-Matter interaction group we study the interaction of light with matter within the context of current, and potential future optical metrology applications, such as laser-induced ultrasonics.
In the Materials & Surface Science for EUV lithography group we study the evolution of surfaces exposed to challenging conditions relevant to nanolithography, including the interaction with gases, radicals, ions, and light. The key method for this research is in situ photoelectron spectroscopy, which allows conclusions on the composition and chemical state of the surface.

Terms of employment
A temporary contract for 38 hours per week for the duration of 4 years (the initial contract will be for a period of 18 months and after satisfactory evaluation it will be extended for a total duration of 4 years). This should lead to a dissertation (PhD thesis). We will draft an educational plan that includes attendance of courses and (international) meetings. We also expect you to assist in teaching undergraduates and master students.
The gross monthly salary, based on 38 hours per week and dependent on relevant experience, ranges between € 2,443 to € 3,122 (scale P). This does not include 8% holiday allowance and 8,3% year-end allowance. The UFO profile PhD is applicable. A favourable tax agreement, the ‘30% ruling’, may apply to non-Dutch applicants. The Collective Labour Agreement of Universities of the Netherlands is applicable.
Besides the salary and a vibrant and challenging environment at Science Park we offer you multiple fringe benefits:
- 232 holiday hours per year (based on fulltime) and extra holidays between Christmas and 1 January;
- multiple courses to follow from our Teaching and Learning Centre;
- a complete educational program for PhD students;
- multiple courses on topics such as leadership for academic staff;
- multiple courses on topics such as time management, handling stress and an online learning platform with 100+ different courses;
- 7 weeks birth leave (partner leave) with 100% salary;
- partly paid parental leave;
- the possibility to set up a workplace at home;
- a pension at ABP for which UvA pays two third part of the contribution;
- the possibility to follow courses to learn Dutch;
- help with housing for a studio or small apartment when you’re moving from abroad.
