Electron Matter Interactions in Transmission Electron Microscopy

The course is lecture based. Lectures will take place from 10h15–12h00 every Tuesday through the spring 2024 semester, in room CM 1 104.

The course will be assessed by individual oral presentations/discussions of a published scientific article that involves one or more of the EM interactions presented in the course. During this exam, the student will be expected to connect the relevant contents of the article to the material seen in the course.

To find a suitable paper, we ask students to find and propose in advance a relevant paper for which approval by the teachers will be needed. 

The exam date is Monday 17 June. The exam will take place in room GR A3 31. Exam schedule:
