The lecture gives an introduction to the physics at surfaces and the methods used in systems where the atomic scale determines the properties. What happens in reduced dimensions and when a drastically reduced number of atoms arrange in well-defined structures. Where are the atoms and the electrons. What are the experimental methods.

The lecture will take place online via MS Teams.
