Abschlussarbeiten und zwei Doktorandenstellen (75% E13)

Unser Gruppe wächst: in unseren neu renovierten und ausgestatteten Laboren können wir Ihnen endlich spannende Themen für Bachelor- und Masterarbeiten anbieten.

(In Kürze) frischgebackenen Masterabsolventinnen und -absolventen bieten zwei Promotionsstellen (75% TV-L E13) finanziert durch die Deutsche Forschungsgemeinschaft ideale Rahmenbedingungen, an spannenden Fragestellungen der integrierten Phononik zu forschen und zu promovieren.

Interesse geweckt? Eine kurze Email an  Professor Krenner genügt und wir freuen uns mit Ihnen gemeinsam mögliche Themen persönlich zu besprechen.

Die Ausschreibungen der beiden Promotionsstellen finden Sie hier:

PhD position in Magneto-Phononics  und PhD position INPhO

Bachelor and MAster Thesis PROJECTS and two PhD positions

The group is growing: join us to conduct cutting-edge research in our newly refurbished labs. We are offering attractive Bachelor or Master thesis projects.

Please contact  Professor Krenner for a personal appointment to discuss possible topics and opportunities.

We are inviting applications for two PhD positions (TV-L E13 75%) supported by  Deutsche Forschungsgemeinschaft (DFG):

Opening PhD position in Magneto-Phononics  and Opening PhD position INPhO

We used out SAW-technology to sort single light quanta – photons – on a chip inside an integrated circuit for light.

Our Research

Our research is centered on the fabrication, investigation and control of novel solid-state nanosystems with tailored optical, electrical and mechanical properties. It is guided by the vision to unify and employ the coherent interaction of the three elementary excitations in the solid state, electrons, photons and phonons – ultimately in the limit of single quanta.

We cover three major areas of modern nanoscience and nanophysics:

  • Quantum-optomechanics: coherent coupling of light, sound and matter in nanoscale circuits on a chip

  • Fabrication, characterization and control of hybrid active nanosystems

  • High-resolution acousto-optoelectronic spectroscopy of emerging solid-state materials

We produced a Video on Youtube introducing examples of cross-disciplinary SAW-applications.

This video was produced by doctoral students (early stage researchers, ESRs) of the Marie Sklodowska Curie Innovative Training Network SAWtrain. This project has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement No 642688.
