FYS-2107 Introduction to Surface Science, 5 cr
Suitable for postgraduate studies.
||Accepted learning assignments.|
After completing the course, the student will be able to recognize the main physicochemical surface properties and to combine them with surface mediated processes such as adsorption and formation of surface compounds. The student will learn how to apply the surface properties to surface engineering technologies (e.g. heterogeneous catalysis, the growth of thin films, nanotechnology, biomaterials). After completing the course, the student will be able to evaluate how the surface mediated processes can be utilized to develop novel, technologically relevant material properties. During the course, the student will learn to solve interdisciplinary research problems related to surface science 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 online learning management system as well as in the form of a research report.

Ohjeita opiskelijalle osaamisen tasojen saavuttamiseksi
The final grade of the course is defined by week performance, Midterm and Endterm electronic exams and a research report that is based on a project assignment, which is to be completed as a result of a team work. The assessment of the course is either numeric on the grade scale of 0 - 5 or Pass/Fail and will be decided together with the teacher and the students at the beginning of the course. The numeric assessment is based on weighting the week performance by 40%, Midterm and Endterm exam results by 40% and the research report by 20%. Instructions how to achieve the learning outcomes of the week performance and the project assignment can be found from the Moodle. This course is based on a blended learning method with 'flipped classroom' type of activities, so please bring your laptop/tablet/smart phone to the learning sessions.
