Kongens Lyngby


In our center we have built a dark field x-ray microscope, installed at the European Synchrotron Radiation Facility, ESRF. Similar to transmission electron microscopy, this allows visualization of the microstructure (grains, domains, dislocations), but now in 3D and nondestructively. At the same time, we can map the local stress. With this microscope we can for the first time directly see how the microstructure evolves inside real life samples. We are looking for an outstanding and motivated candidate to push the boundaries of the new technique by simulations and experiments.

In the center: 'The Physics of Metal Plasticity' we combine X-ray simulations and experiments with dislocation dynamics simulations to see how dislocations (defects) self-organize during deformation of metals. The aim is to provide a first principles description of mechanical properties such as strength.

This work is also part of a new Danish Center-of-Excellence on hard materials in 3D, SOLID. Here you will be interacting with 15 other PhDs, all exploiting the latest 3D methods based on large scale x-ray and neutron facilities, within in a broad range of fields spanning ferroelectrics, martensitic transformation, biomineralization and archeology.

Responsibilities and qualifications

Your research will be key for advancing the instrument at ESRF into a real microscope, with modalities similar to a TEM.

Your responsibility will be full scale optical simulation of the microscope coupled with interfacing to dislocation dynamics simulations, design and optimisation of modalities for visualization of the dislocations, and demonstration experiments and associated data analysis.

You are excited about fundamental science, and we expect that you enjoy being part of a team, that you have sense of humour, is a good problem solver and that you can work efficiently and independently.

For this position we favour candidates with a degree in physics or materials science. You should
  • Have a solid grasp of diffraction, solid state physics and linear algebra
  • Understand Fourier optics
  • Have hands on experience with simulations with proven experience with programming, e.g. Python


You must have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree.

Approval and Enrolment

The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see the DTU PhD Guide. http://www.dtu.dk/english/Education/PhD/Rules/PhDguide

Assessment

The assessment of the applications will be made by Professor Henning Friis Poulsen, DTU Physics and Profesor Grethe Winther, DTU Mechanical Engineering.
