Bachelor projects

The Chair of Applied Physics offers the possibility to do a bachelor project with experimental focus and on cutting-edge topics.

Graphene is a single graphite layer. It constitutes an ideal two-dimensional material. The electrons in graphene reveal exceptional properties, which makes this solid highly interesting for fundamental physics as well as for applications. At the Chair of Applied Physics, we grow epitaxial graphene of very high quality. We fabricate tailormade devices by electron beam lithography for novel experiments. We focus in particular on the unconventional physics of the electrons in graphene.

Silicon carbide (SiC) is a wide-bandgap semiconductor with superior electrical breakdown field strength and superior heat conductivity comparable to copper. Due to these properties, SiC is used for the fabrication of energy efficient power devices, which are required in traction, electrical vehicles, power inverters and switching power supplies. We investigate the physics of defects at interfaces and in the bulk, which determin the properties of this semiconductor.

The term “molecular electronics” comprises the idea to build electronic devices from single molecules. Today, charge transport through molecules at the nanoscale is far from beeing fully understood. At the Chair of Applied Physics, we are able to contact and investigate individual organic molecules using atomically sharp gold tips or graphene nanojunctions. For the sample fabrication, we employ electron beam lithography and UHV metal deposition techniques.

During the last decade, research activities in the terahertz (THz) range became more and more important in order to close the so-called “THz gap” in the electromagnetic spectrum (100 GHz to 10 THz). In particular, pulsed and cryogenic systems have been developed. However, continuous wave (CW) sources have been neglected despite the fact that there is a strong need for tunable and powerful CW sources. Our n-i-pn-i-p photo mixer concept allows the development of powerful CW THz sources and systems and we are pushing forward the research in this area.

When starting a bachelor project, you will become part of our team at the Chair of Applied Physics. Experienced PhD students will support you. After a period of initial training, you will be able to prepare samples and to perform measurements by yourself.
