After successful completion of this module, the student is able to

·      remember basic concepts of the analysis and control of matter at the nanoscale

·      understand the state-of-the-art experimental techniques

·      discuss how specific surface science questions are addressed in practice

·      recognize the cutting edge of surface and nanoscale science

·      develop insight in current research and emerging domains

Basic knowledge on solid state physics, quantum mechanics, surface and nanoscale science, as well as curiosity and openness for an interdisciplinary field is expected.

In classroom lectures the teaching and learning content is presented and explained in a didactical, structured, and comprehensive form. This includes basic knowledge as well as selected current topics from a very broad research field. Universal methodic and physics concepts are highlighted by cross referencing between different topics. Crucial facts are conveyed by involving the students in scientific discussions to develop their intellectual power and to stimulate their analytic thinking on physics problems. Regular attendance of the lectures is therefore highly recommended.

The examples as well as regular self-study of personal notes from the lectures and recent review articles referenced in the course are an important part of the learning process by the students. Such post-processing and rationalization of the teaching content is indispensable to achieve the intended learning results that the students develop the ability of explaining and applying the learned knowledge independently. Furthermore, the preparation of a seminar talk on a selected, recent research article will help the students to explain and apply the learned physics and methodology knowledge.

Lab visits and excursions, including discussions with scientists in the field of surface and nanoscale science, will convey the practical relevance and implementation of the experimental techniques and yield insight in current resear4ch areas and emerging domains.
