In teaching Prof Bell's TEM course, AP291, I have summarized the process of making a good cross section sample with hand polishing followed by ion milling. Thank to all the students who provided the precious pictures of the whole process.
This procedure is primarily for creating the cross section TEM sample for thin film (ideally 1nm~100nm). It might not work well with very thick films.
Please let me know if there is anything you think I can improve this manual. Thank you very much.
