Checklist for admitted students

  1. Activate your university account

    The first step in being able to register and gain access to all the university's IT services.

  2. Register at your department

    Registration can be done in different ways. Read the instructions from your department below.

  3. Read all the information on this page

    Here you will find what you need to know before your course or programme starts.

IMPORTANT

Your seat may be withdrawn if you do not register according to the instructions provided by your department.

Welcome activities

Stockholm University organises a series of welcome activities that stretch over a few weeks at the beginning of each semester. The programme is voluntary (attendance is optional) and includes Arrival Service at the airport and an Orientation Day, see more details about these events below.
Your department may also organise activities for welcoming international students. More information will be provided by your specific department.

Note! Information on how teaching will be carried out will be published on kemi.su.se .

The course deals with how analytical electron microscopy (EM) can be used in material chemical studies, including nanomaterials. Both scanning electron microscopy (SEM) and transmission electron microscopy (TEM) will be covered.

The course provides a description of the construction of the TEM and the SEM and the basic physics behind image formation. Also included are electron diffraction techniques based on kinematic and dynamic diffraction, image formation based on mass contrast (low resolution), light field microscopy, dark field phase contrast at atomic resolution.

The course deals with how images taken with these techniques can be interpreted, eg. indexing and determination of unit cells of crystalline materials as well as theoretical calculations and image analysis.

It also provides an introduction to different preparation methods for EM. The course also deals with how chemical and spectroscopic analysis techniques in SEM and TEM can be used to obtain information on chemical composition using energy dispersive X-ray spectroscopy.

 

  • Course structure

    After completing the course, the student is expected to be able to:

    • explain the basic principles of how transmission electron microscopes (TEMs) and scanning electron microscopes (SEMs) are designed and work
    • propose suitable sample preparation methods for EM studies
    • interpreting electron diffraction patterns and TEM imagesPage 1/2
    • describe how to obtain information about the chemical composition of a material
    • describe what type of material chemical problems can be solved with analytical EM
