Scientific Internship: Exploring the Surfaces of High-Entropy Alloy Thin Films

Date posted February 10, 2021
Type Scientific internships
In this project you will try to understand what is unique about high-entropy materials – a novel class of high-performance compounds – by looking at their surface properties.
You will learn how to use ultra-high vacuum equipment for the growth and analysis of materials in ultra-clean environment. Together with a PhD student you will grow layers of a high-entropy alloy using pulsed laser deposition, a technique using high-intensity laser pulses to ablate material and deposit it onto atomically clean single crystals. You will probe the first few nanometers of the sample using the surface-sensitive technique X-ray photoelectron spectroscopy to analyze the purity of your films, their composition, and the oxidation state of the elements. While performing the measurement, you will heat the layers and follow the changes occurring at the surface.

About the group

At the Advanced Research Center for Nanolithography (ARCNL) we carry out exciting fundamental physics research at the highest possible level with relevance to key technologies in nanolithography. We contribute to the production of ever smarter and smaller electronics, while at the same time pushing the boundaries of our fundamental insight into the workings of nature. During this internship you will be embedded in the research group for Materials and Surface Science for Extreme Ultraviolet Lithography.


You have or will soon have a Bachelor’s degree in physics or a related field and will participate in a Master study during the entire internship duration. The internship must be a mandatory part of your curriculum. You have a nationality of an EU member state and/or you are a student at a Netherlands University. Please note: As of January 2021 the UK is no longer an EU member state. You must be available for at least 5 months.

Terms of employment

At the start of the traineeship your trainee plan will be set out, in consultation with your ARCNL supervisor.
