The Chair of Advanced Transmission Electron Microscopy at the Faculty of Physics and Astronomy is looking for a

postdoc (m,f,x) in four-dimensional scanning transmission electron microscopy, for 3 years, 39.83 hours per week, TVL E13

The chair of Advanced Transmission Electron Microscopy develops techniques in the electron microscope to study material phenomena down to the atomic level. The main working areas are atomic resolution microscopy, spectroscopy, 4D-STEM, in situ microscopy and data analysis. We use these methodologies to study interfaces in materials, novel catalysts, emerging magnetic materials and advanced energy materials.

We are seeking a postdoctoral researcher (f/m/x) with a strong background in scanning transmission electron microscopy and related data analysis / simulation. The successful candidate (f/m/x) is expected to have demonstrated a high level of proficiency in developing and applying 4D-STEM methods using pixelated electron detectors. The candidate is required to have experience in using open-source toolboxes (such as Hyperspy, Pyxem or Py4DSTEM) for data analysis and to develop new analysis workflows.

Your tasks:

  •  Implement of 4D-STEM experiments using pixelated electron detectors
  • Establish magnetic domain imaging by Lorentz 4D-STEM
  • Develop fast, automated crystal orientation mapping
  • Implement atomic resolution 4D-STEM experiments for differential phase contrast imaging and electron ptychography
  • Develop novel data analysis approaches of 4D-STEM datasets including crystal orientation mapping, differential phase contrast and electron ptychography
  • Establish automated 4D-STEM experiments

Your profile:

  • PhD degree in physics, applied physics or materials science
  • Strong experience in scanning transmission electron microscopy
  • Hand-on experience in TEM sample preparation, including FIB
  • Solid track-record in 4D-STEM experimentation using pixelated detectors

The Ruhr-Universität Bochum is one of Germany’s leading research universities, addressing the whole range of academic disciplines. A highly dynamic setting enables researchers and students to work across the traditional boundaries of academic subjects and faculties. To create knowledge networks within and beyond the university is RUB’s declared aim.


The Ruhr-Universität Bochum stands for diversity and equal opportunities. For this reason, we favour a working environment composed of heterogeneous teams, and seek to promote the careers of individuals who are underrepresented in our respective professional areas. The Ruhr-Universität Bochum expressly requests job applications from women. In areas in which they are underrepresented they will be given preference in the case of equivalent qualifications with male candidates. Applications from individuals with disabilities are most welcome.
