Scanning probe methods like scanning tunneling microscopy allow for unique insights into physical phenomena on the atomic length scale. Moreover, in combination with the various manipulation capabilities of the technique, structural, electronic and magnetic surface properties can not only be observed but also artificially designed atom-by-atom. The aim of the lecture is to teach the basics of surface physics and scanning probe methods, enabling the students to understand the results of current research activities that will be presented as well.
The lecture will give a good overview of both fundamentals and current research in the fields of surface science, electronic structure and magnetism in reduced dimensions. After successfully completing this module the students will be able to understand experimental sample preparation procedures as well as experimental techniques of low-temperature physics and different surface science characterization tools using electrons and photons. A focus of this lecture will be put on magnetic atoms, nanostructures, and films on single crystal surfaces, enabling the students to identify different magnetic interactions responsible for the emergence of magnetic order. (Spin-sensitive) scanning probe methods will be discussed in terms of their basic working principles, their imaging and manipulation capabilities up to recent developments in terms of ultimate spatial, time- and energy resolution. |
