À propos du cours

Learn about the fundamentals of transmission electron microscopy in materials sciences: you will be able to understand papers where TEM has been used and have the necessary theoretical basis for taking a practical training on the TEM. This course provides a comprehensive introduction to transmission electron microscopy (TEM) in the field of materials science. For an instrument operated by a single user, modern TEM provides an analytical platform with unsurpassed versatility, giving access to structural and chemical information from the micrometer to the sub-angstrom scale. In a thin, electron-transparent sample one can measure the crystallinity, grain structure, size, and defects, and the chemical composition. The crystal lattice can be imaged with atomic resolution, allowing observation of grain boundaries and interfaces. It is the only direct structural analysis method for studying nanoparticles. With this course you will gain a deep understanding of modern TEM and the connection between: - the optics and operation of the instrument; - the physics of electron-matter interactions; - insights into the materials properties of the sample. This gives the background to: - identify TEM techniques suitable to solving specific scientific problems; - interpret TEM data presented in articles; appreciate the impact of technological advances that have, for instance, led to sub-angstrom resolution by aberration correction. It can also be the basis for subsequent practical training on this remarkable instrument, and a stepping stone towards learning very advanced techniques with magical names like “dark field holography” or “angular resolved electron energy-loss spectroscopy”. Recommended background: Basics of crystallography and diffraction, college optics (construction of ray diagrams) are absolutely mandatory prerequisites; Fourier optics, more advanced crystallography and solid state physics are of great advantage....

Amazing content, the concepts were super interesting to learn and think about. Challenging but also invigorating - lots of diagrams to draw and visualise TEM images.

It was really tough to follow the material, specially the Quiz questions. Not a course to improve our knowledge more it was like tough exams to determine the first rank of a competition.

not an "easy A"

i had to work very hard to successfully complete this course

but i feel rewarded b/c of it to earn the certificate

This course is really very helpful for me. I learnt so many things about TEM. Study material are very well arranged. They organise the whole course in a nice way and present it among learners. I just want to say Thank you to my dear my prof.

Thanks a lot!
