Interaction of electrons with solids, types of electron microscopes. Imaging in a transmission electron microscope (TEM), specimens for the microscopy. Electron diffraction (scattering on an atom and a lattice, point diffraction pattern, Ewald construction, deviation from the exact reflection condition). TEM diffraction contrast (extinction contours, contrast of crystal defects). Kinematical and dynamical theory of contrast. Kikuchi lines. Practical tasks of electron diffraction and TEM. Application of stereology. High resolution electron microscopy. Microdiffraction, CBED. Scanning electron microscopy (SEM),analytical methods in electron microscopy (X-ray microanalysis, backscattered electron diffraction). Practical demonstrations.
