Learning unit contents
The course describes the physical principles and functioning of the major instruments in modern electron microscopy. It includes the following chapters :
1) Introduction and history of electron microscopy
2) Electron-material interactions (scattering and resulting particulate and electromagnetic radiations)
3) Instrument parts (vacuum pumps, electron guns and detectors, electromagnetic lenses)
4) Instrument operation and imaging in : - scanning electron microscopy (SEM in high vacuum, low vacuum, controlled pressure conditions including "environmental" or "wet" modes - transmission electron microscopy (TEM: different image, diffraction and high resolution modes) - scanning transmission electron microscopy (STEM: principles, advantages and disadvantages)
5) Analytical electron microscopy - X-ray microanalysis (EDS) - Electron energy-loss spectroscopy(EELS) and energy filtering (EFTEM)
The course includes a practical learning on the preparation of samples for SEM/TEM as well as training sessions on the equipments of the Center of Applied Technology in Microscopy (CATµ-ULg).
This part constitutes an evaluated personnal work on a defined subjet, preferentially dedicaced to an original scientific question.
