Internship: Modelling atomic adsorption on metal surfaces

Chemistry & materials science


In a nutshell


Veldhoven, Netherlands


No experience (Student)



Job Category

Chemistry & materials science, Physics


Are you a Master student in Chemical Engineering or Physics with a strong interest in surfaces and electronic structure calculations? Then this assignment could be interesting for you.

Job Mission

Ongoing miniaturization in the semiconductor industry leads to smaller and smaller chip structures, which is currently reaching a size regime where the interaction between materials needs to be understood of “atom by atom”. More and more atoms form interfaces rather than being part of bulk structures. Chemical reactions at those interfaces can thus no longer be described by thermodynamics developed for the continuum scale. Instead, the adsorption of individual atoms and their lateral interactions on the surface need to be described explicitly. For instance, a study on the formation of oxide layers on aluminum [1], describes a self-limiting growth of the oxide layer because the adsorption energy of in this case oxygen decreases with increasing layer thickness. The objective of the project is to transfer insights from that paper to more general the growth process of other adsorbates on noble metals.

Job Description

You will build a density functional theory (DFT) based model to describe the adsorption and interaction of adsorbate atoms and thin layers on metals. The model will enable you to describe the change of the adsorption energy as function of the surface coverage and layer thickness.

This project is done for ASML at the University of Leiden.


You are a Master student in Chemistry or Physics with a strong interest in surfaces and electronic structure calculations (Hartree-Fock and/or DFT). Good understanding of chemical bonding at the quantum mechanical level are mandatory. Expertise in DFT calculations (e.g. with VASP, Quantum Espresso, CASTEP) is an advantage. Ideally you have already followed the MSc lecture “Density Functional Theory in Practice” https://studiegids.universiteitleiden.nl/courses/97135/density-functional-theory-in-practice-dip

This is a Master graduation or apprentice internship for 5 days a week with duration of 6 months. The start date can be discussed.

Please keep in mind that we can only consider students (who are enrolled at a school during the whole internship period) for our internships and graduation assignments.

Other information

What ASML offers
Your internship will be in one of the leading Dutch corporations, gaining valuable experience in a highly dynamic environment. You will receive a monthly internship allowance of 500 euro (maximum), plus a possible housing or travel allowance. In addition, you’ll get expert, practical guidance and the chance to work in and experience a dynamic, innovative team environment.

ASML: Be part of progress
We make machines that make chips – the hearts of the devices that keep us informed, entertained and safe; that improve our quality of life and help to tackle the world’s toughest problems.

We build some of the most amazing machines that you will ever see, and the software to run them. Never satisfied, we measure our performance in units that begin with pico or nano.

We believe we can always do better. We believe the winning idea can come from anyone. We love what we do – not because it’s easy, but because it’s hard.

Students: Getting ready for real-world R&D
Pushing technology further is teamwork, and our R&D team is more than 5,500 people strong, with major sites on three continents. Dozens of diverse, interdisciplinary teams work in parallel to meet a challenging development schedule.

In such an environment, your colleagues may be sitting next door, or they could be thousands of kilometers away in a different country, or even working for a different company.

An internship at ASML is your opportunity to get to know this world of industrial-strength R&D and get a feel for that excites you most. Will you design a part of the machine, or make sure it gets built to the tightest possible specifications? Will you write software that drives the system to its best performance, or work side-by-side with the engineers of our customers in a fab, optimizing a system to the requirements of the customer?

How will you be part of progress?
