ASML
Graduation assignment: Investigate molecular dynamics for calculations between surfaces in vacuum
Introduction
This is a graduation assignment for a master's student in Applied Mathematics, Physics or Mechanical Engineering who has focused on working with molecular dynamics simulations, has experience with LAMMPS software and is interested in investigating molecur dynamics simulations for calculations of effective sheer strength between surfaces in vacuum.
Job Mission
ASML is constantly pushing the limits of technology into areas where nobody has gone before. Within ASML the Research Department is responsible for innovation and improvement of ASML machines. The Tribology project team within the Flow and Temperature group is in charge of the development of fundamental knowledge in friction and wear and consequent optimization of tribological performance of ASML machine parts.
Currently, comparison of experimental measurements and theoretical simulations shows that there is a direct relation between friction, effective shear strength and the contact area. Information on the contact area can be obtained from the Atomic Force Microscope measurements and Boundary Element Method simulations. The effective shear strength can be calculated using Density Functional Theory (DFT) based Molecular Dynamic (MD) simulations, however, this is a time consuming process. The goal of the project is to access the feasibility of using the classical Molecular Dynamic simulations instead of DFT to calculate the effective shear strength between surfaces in vacuum.
There are two main goals of the project:
- The first is to perform a literature search for existing potentials for a specified pair of materials.
- The second goal is to apply selected potentials using classical MD simulation to predict the effective shear strength in the contact. This will be compared to the values obtained in an experiment.
You are a master’s student in Applied Mathematics, Physics or Mechanical Engineering with a focus on molecular dynamics simulations. You have experience with LAMMPS software and your communication skills in English are excellent.
This is a graduation internship for 5 days a week with a minimum duration of 8 months. The start date is as soon as possible.
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.
