Learning outcomes

After completing the course, the student will be able to define the physical operation principles of electron spectroscopy methods such as XPS, AES, ARUPS and NEXAFS. The student will learn how to apply the electron spectroscopy methods to identify elemental distribution of solid surfaces, nanostructures and molecular structure of surface compounds. During the course, the student will learn to solve surface analytic research problems in tutorial learning sessions (groups of 4-6 students) based on the shared expertise of the group members. The student will master the skills required to report the results of the learning assignments using Moodle learning management system as well as in the forms of a research report and a seminar presentation.

Evaluation criteria for the course

The assessment of the course is either numeric on the grade scale of 0 ... 5 or "Pass/Fail". The assessment method will be decided together with the students at the beginning of the course. The numeric assessment is based on a literature exam. If the student demonstrates thorough understanding of the core content, s/he may pass the course with the grade 3. In order to achieve grade 4, the student must also demonstrate competency in the points specified in column "Complementary knowledge". The student may achieve grade 5, if s/he demonstrates good command of the points specified in column "Specialist knowledge". If there are minor shortcomings regarding the core content, the student may receive the grade 1 or 2, depending on the number of flaws. If there are significant shortcomings regarding core content, the student will not pass the course. The assessment of the course can also be "Pass/Fail". The student can earn the passing grade, if s/he has completed all the learning assignments in a satisfactory manner.
