Probing Topological Materials with Atom-Surface Scattering

Dissertation, Diplomarbeit

The aim of this project is to understand the properties of novel and unusual surfaces, so-called topological insulators and Weyl semimetals, for which few dynamical measurements exist. Topological insulators are a class of quantum materials. Its surfaces exhibit good metallic character while the bulk remains insulating. Potential applications are ranging from spintronics to quantum computation. The surface structure and dynamics of these promising material surfaces will be studied using helium atom scattering. While a part of the project should be of experimental nature the main focus of the project can either be on the experimental side or using a more theoretical approach, depending on the individual interests. If the student is interested in spending some time abroad the group my also be able to organise either a research stay at the University of Cambridge (for experimental measurements) or at the Donostia International Physics Centre (for theoretical calculations).
