Learning outcomes

Students acquire knowledge of the fundamentals and methods for the electrochemical preparation of nano-structures. The topic of the module serves as an example to illustrate the connection between basic and applied sciences and to demonstrate the methods of attaining new perceptions. Additionally the module supports presentation skills and further competences as accurateness, endurance and curiosity.

Assessment

• Written examination, 90 minutes

Remarks

• Study programme Physics M. Sc.: Compulsory elective module in specialised modules "Applied Physics". Self organised studies: • re-work of the lecture by means of English literature.
