Group of Prof. Müller-Caspary - Faculty for Chemistry and Pharmacy

DGE study group on DPC

The German Society for Electron Microscopy (DGE) supports topical and informal exchange in the form of "study groups". The Study Group Differential Phase Contrast (DPC), i.e., the Arbeitskreis DPC is one of those and currently being organised by Knut Müller-Caspary (Speaker, k.mueller-caspary@cup.lmu.de).

Following the tradition of the DGE study group concept, the Study Group DPC is dedicated to

  • Bringing together electron microscopists interested in STEM-based phase contrast imaging and phase retrieval
  • Providing a forum dominated by informal discussions on methodology performance, reliability and development
  • Allowing the mutual exchange of ideas in the spirit of openness
  • Reflecting current results and publications
  • Discussing the present state and potential future directions in the field of STEM DPC

Contrary to "print-ready" mature conference presentations, this meeting is governed by its informal character. It explicitly welcomes work-in-progress contributions with a focus on open questions, problems in practical experiments and data interpretation, as well as working out methodological pitfalls.

Although the study group's title is "DPC", it nowadays refers to the broader field of "4D STEM" and the question what can be learned from the combination of real and diffraction space data. Consequently, topics such as

  1. Differential Phase Contrast (DPC) STEM using segmented detectors
  2. First Moment STEM
  3. Mapping electric and magnetic fields
  4. Phase retrieval by direct and iterative methods (e.g. ptychography)
  5. Further relevant topics from the field of pixelated STEM.
