LNNano - Brazilian Nanotechnology National Laboratory

Electron Microscopy Courses at Unicamp-FEM

The researchers of LNNano usually conducts the course Transmission Electron Microscopy: theory and practice offered by the Post-Graduation office of the Physics Institute Gleb Wataghin (IFGW) at Unicamp (IFGW/Unicamp). Addittion to classes this course also include practical lessons in electron microscopies at the LNNano. This course often opens registration in the Special Student category.

The Special Student category is for graduate students who are not registered in Post-graduate courses at Unicamp and wish to take a course in one or more isolated disciplines within the academic year.

The registrations in this category are subject to the acceptance of the Professors and have limited vacancies in each discipline.

The disciplines menu is as follows:

  1. Introduction: microscopy and idea of image;
  2. Types of electron microscopes: scanning, transmission, scanning and transmission;
  3. Electronic optics: magnetic lenses, electron sources, detectors, electron-material interactions: scattering, cross-sessions;
  4.  Electron Diffraction: introduction
  5. Basic crystallography: crystalline structure, reciprocal space;
  6. Diffraction of crystals: finite crystals and thin films cases;
  7. Diffraction cinematic and dynamic: Kikuchi lines;
  8. Transmission Electron Microscopy: general aspects;
  9. Formation of images: cinematic and dynamic theory;
  10. Conventional microscopy: two beam, weak beam, defective images;
  11. High resolution microscopy: (HRTEM): phase contrast;
  12. Contrast Transfer Function: resolution limit;
  13. Scanning microscopy in transmission (STEM): elastic scattering, Z-contrast
  14. Sample preparation: general aspects, cross-sections;
  15. Microscopic analyses: spectroscopy of X-rays and electrons;
  16. Spectroscopy of characteristic X-rays (EDS): qualitative and quantitative analysis;
  17. EDS: Micro and Nano analyses: general aspects;
  18. EDS: Determination of chemical composition;
  19. EDS: Spatial resolution and limits of detection;
  20. Chemical mapping and spectral imaging;
  21. Spectroscopy by loss of electron energy (EELS): dielectric properties and fine structure;
  22. Electronic structure of solids: Study by EELS;
  23. Advanced applications and today trends;
  24. Perspectives.
