A practical introduction to scanning electron microscopy

UPDATE: The lecture on EDX will be given at a later time announced as soon as possible!

The course will cover the basic modes of operation of SEM, sample preparation, x-ray spectroscopy and a description of the capabilities of our in-house microscope and other extended features. The course includes 4 hours of lectures and 4 hours of practical hands-on SEM imaging in small groups after which the students will be allowed to book and use the instrument on their own. To sign up please fill in the form here.

The schedule tentatively looks as follows:

First lecture, Thu 27 Feb, 10-12 Conference room.

  • Introduction
  • Principles of operation
    • Back-scattered vs secondary electrons
    • Different detectors

Second lecture,  Tue 3 March 2020, 13-15 Conference room.

  • Sample preparation
  • EDX/WDX spectrocopy (given by Dr. Marcin Hołdyński)

The final part of the course is a practical training in small groups (3 students) where handling of the microscope, mounting samples, adjusting the image etc. will be shown and tested.

For passing the course the students should perform measurements on a test sample and write a short report showing the ability to take images and analyse the information from these.

Lecture slides (might still change):
SEM course 1
SEM course 2
EDS

Signing up for the practicals is done with the doodle here. First come – first serve, but please try to fill up the groups.
