Physics | Material Science Internship: Investigate pre-adsorbed species on oxide chemistry
Chemistry & materials science
In a nutshell
No experience (Student)
Chemistry & materials science, Physics
Are you a master student with background in Physics, Material Science or Chemistry? Do you have experience with Python and C? Then this internship assignment could be interesting to you!
ASML brings together the most creative minds in science and technology to develop lithography machines that are key to producing faster, cheaper, more energy-efficient microchips. We design, develop, integrate, market and service these advanced machines, which enable our customers - the world’s leading chipmakers - to reduce the size and increase the functionality of their microchips, which in turn leads to smaller, more powerful consumer electronics.
At ASML-Research, we have recently found a novel method to reduce the oxidation level of the metal surface. Diminution of the oxidation level is tailored by a chemical treatment process. These investigations are mostly done by a combination of modeling and experiments within the project. We plan to provide the mechanistic understanding of how this chemical treatment prevents the surface from oxidation. Further research via computational methods is needed to elucidate this finding at the atomic scale and devise possible strategies to optimize the chemical treatment from the gained understanding.
The goal of this internship assignment is the modeling of adsorption as dissociation of O species, on chemically treated metal surfaces, to understand the impact of pre-adsorbed species on oxide chemistry.
This proposal intends to:
- Investigate the adsorption kinetics of atomic and molecular oxygen, on well-defined model systems, that are of relevance in the aforementioned context;
- Carry out standard density functional theory (DFT) calculations, based on the generalized-gradient approximation (GGA). This is for the exchange-correlation functional in a plane-wave implementation, to obtain the adsorption energy profile for different adsorption sites;
- Use appropriate transition state analysis techniques (e.g. nudge elastic band) for the calculation of energy barriers.
Despite the GGA-inherent error, use the calculated energy barriers to estimate oxygen adsorption rates for the considered model systems considered;
- Thus, provide valuable mechanistic insights into the diminution of oxidation due to the chemical treatment at the atomic scale.
- Month 1: Definition of plan for the computational simulations;
- Month 5: Comparison with our experimental data. Conclusion on reliability and error of the modelling approach and how to improve it;
- Month 9: Finished report and given final presentation.
The work is going to be carried out in collaboration with the Theoretical Chemistry group of Leiden University.
- You are a master student with educational background in Physics, Chemistry or Material science;
- You are looking to do your graduation project or gain work experience;
- You have experience with programming languages Python and C;
- You are flexible to travel to Leiden;
- You are available to do a full-time internship with a minimum duration of 9 months.
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.
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 based on your educational level and number of days per week, plus a possible housing or travel allowance. More information on the allowances can be found on our website. In addition you will 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 applications 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. At ASML we are always pushing technology further.
Students: Getting ready for the real-world
Teamwork is key within ASML. Our R&D team is more than 5,500 people strong and worldwide we form one big team with over 23,000 employees. These colleagues have 123 different nationalities and work at our major sites on three continents.
Dozens of diverse, interdisciplinary teams work in parallel to meet a challenging development schedule. In this inspiring 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 and get a feel for that excites you most. Use your education, gain real-life working experience and explore the world of high-tech – all at the same time.
How will you be part of progress?
