Doctoral Position on Ultrafast Charge and Exciton Processes in Organic Semiconductors (f/m/x)
Institute of Physics II

We are one of the largest and oldest universities in Europe and a major employer in our region. Our diverse range of subjects, dynamic research areas, and central location in Cologne attract students and researchers globally. We offer numerous career opportunities in science, technology, and administration.

This position is available in the research group ‘Optical Condensed Matter Science’ (https://ph2.uni-koeln.de/arbeitsgruppen/loosdrecht) at the Institute of Physics II, part of the physics department. It is part of the DFG-funded research training group ‘Template-Designed Organic Electronics’ (TIDE), which offers a multidisciplinary research environment and a structured doctoral program (https://tide.uni-koeln.de).
The aim of the doctoral project is to enhance our understanding of ultrafast exciton and charge processes in organic semiconductor materials.

YOUR TASKS

• Study exciton and charge carrier dynamics in organic and hybrid semiconductors using ultrafast optical spectroscopy, advanced data analysis, and modelling.
• Present research results at seminars and conferences, and publish in peer-reviewed journals.
• Actively participate in TIDE research training group events and training courses (https://tide.uni-koeln.de/home).
• Teach and supervise Bachelor’s and Master’s students.

YOUR PROFILE

• Master’s degree in physics, focusing on condensed matter or molecular physics.
• Highly motivated with experience in ultrafast lasers and time-resolved optical spectroscopy.
• Skilled in advanced data analysis and interpretation using Python, Mathematica, or other programming languages.
• Preferably experienced with organic and/or hybrid semiconductors.
• Excellent written and spoken English communication skills.
• Ability to work independently and collaboratively in a team.

WE OFFER

• An inspiring, collaborative, and international research environment with state-of-the-art ultrafast spectroscopy facilities.
• A diverse working environment with equal opportunities.
• Support for balancing work and family life.
• Extensive advanced training opportunities.
• Occupational health management offers.
• Flexible working time models.
• Opportunity to work remotely.
