Content

This course will present the fundamentals of electron–matter interactions, as occuring in the energy range available in modern transmission electron microscopes, namely 60-300 keV electrons. Diffraction and high-resolution image formation as well as electron energy-loss spectrometry will be covered.

Week 2: Elastic scattering by atoms and crystals. Bloch wave theory. (DA)

Week 3. Elastic scattering: kinematical and dynamical diffraction. (DA)

Week 4: Advanced diffraction, thermal diffuse scattering. (DA)

Week 5: Eastic scattering: phase contrast. (TL)

Week 6: Phase contrast, high resolution imaging. (TL)

Week 7: Phase contrast, holography and other phase retrieval methods. (TL)

Week 8: Simulation software for imaging and diffraction. (TL and DA)

Week 9: Inelastic scattering, introduction. (CH)

Week 10: Inelastic scattering: core loss spectroscopy, experiments and theoretical simulations. (CH)

Week 11: Inelastic scattering: low loss EELS. (CH)
