Physiker (m/w/d) (Physiker/in)

PhD Position (f/m/x)
Faculty of Mathematics and Natural Sciences
Humboldt Centre for Nano- and Biophotonics | Gather Lab

We are one of the largest and oldest universities in Europe and one of the most important employers in our region. Our broad range of subjects, the dynamic development of our main research areas and our central location in Cologne make us attractive for students and researchers from around the world. We offer a wide range of career opportunities in science, technology, and administration.

Organic light-emitting diodes (OLEDs) are a popular class of semiconductor devices that have made their way into everyday technologies such as smartphone and television screens, miniaturised devices for biomedical research, and to other specialised applications. However, our current understanding of the key factors that affect their performance is limited by the fact that most of the characterisation techniques used in the field obtain average properties of what in reality is an ensemble of molecules.

The aim of this project is to study the influence of molecular disorder on the light emission properties of individual molecules doped into state-of-the-art materials used in OLEDs. The project will apply single-molecule microscopy and spectroscopy techniques to obtain information about the degree of order of OLED materials at the nanoscale in thin films, as well as how such order/disorder impacts the orientation and photoluminescence of emitter molecules. It will involve state-of-the-art OLED fabrication and photophysical characterisation techniques, including a strong focus on single-molecule microscopy and spectroscopy studies of organic light-emitting molecules, as well as close collaboration with theoreticians from internationally renowned research groups.

We are looking for a suitable candidate to carry out this exciting and challenging project, which will bring unprecedented information about structure-property relationships in this popular class of organic semiconductor devices. YOUR TASKS

Fabrication of solution-processed and thermally evaporated samples for single-molecule microscopy and spectroscopy
Construction and optimization of single-molecule microscopy setups
Development of image- and signal-processing software for single-molecule microscopy and spectroscopy data
Analysis of single-molecule microscopy data in collaboration with theorists from other institutions
YOUR PROFILE

You should have obtained (or be about to obtain) a Master‘s degree (or equivalent) in Physics, Physical Chemistry, Material Science, or a closely related subject with excellent results.

PhD position (f/m/x) in Biological Physics
Institute for Biological Physics | Group Maier

We are one of the largest and oldest universities in Europe and one of the most important employers in our region. Our broad range of subjects, the dynamic development of our main research areas and our central location in Cologne make us attractive for students and researchers from around the world. We offer a wide range of career opportunities in science, technology, and administration.

Bacteria are unicellular organisms, yet they can form structured communities called biofilms. Researchers in the Maier group study collective effects in biofilms combining tools from physics and microbiology. The specific research project focuses on the formation of extracellular DNA networks in early biofilms and its role in biofilm mechanics and antibiotic tolerance.
