Synopsis:

Inelastic scattering processes with energy losses are often element-specific and so they are used for chemical analysis in the transmission electron microscope. The course deals with the theory of the electron scattering, electron energy loss spectroscopy,energy dispersive X-ray spectroscopy and cathodoluminiscence.

Requirements:
Syllabus of lectures:

1. Introduction to analytical methods

2. Elastic scattering of electrons - Rutherford scattering, scattering on shielded potential, Bragg scattering, scattering on phonons

3. Inelastic scattering of electrons - Bethe theory, dielectric formalism, plasmon excitations, differential cross-section, Kramers-Kronig analysis, multiple scattering, ionization edges, energy loss near edge structure (ELNES)

4. Electron energy loss spectroscopy (EELS) – spectrometer, energy resolution, detection of electron losses, spatial resolution

5. Energy filtered TEM – zero loss filtering, plasmon filtering, elemental mapping

6. Energy dispersive spectroscopy of characteristic X-rays (EDX) - spectrometer, interaction volumes, artefacts

7. Cathodoluminiscence - description of the spectrometer, diffraction on a slit, diffraction on a grid, pair electron-hole recombination, Cerenkov radiation, transition radiation

8. Chemical microanalysis (EELS, EDX)

9. Current research topics - plasmonics, phase manipulation, imaging of atomic orbitals
