In this workshop two free software packages for simulating and processing TEM images and diffraction patterns (STEM_CELL and QSTEM) will be introduced.
The workshop will start by shortly explaining the fundamental concepts of TEM/STEM image simulation, such as crystallography (space groups, symmetries), multislice theory, (partially coherent) imaging theory, linear theory of HAADF simulation, and the frozen phonon approximation.
This introduction to basic principles will be followed by demonstrations of the STEM_CELL and QSTEM software packages. Participants are encouraged to bring along their own laptops and will be given live demonstrations of the following tasks:
building atomic structure models
building complex super structures to match your experimental images
simulating HRTEM images
simulating BF/ADF/HAADF/ABF-
simulating electron diffraction patterns (SAD and CBED)
analyzing strain from HRTEM or STEM images by the GPA technique
Quantitative analysis of composition by HAADF (if time permits)
Organised by Christoph Koch and Vincenzo Grillo.
