Doctoral Research Positions

by the end of the year. We offer part-time positions (50-75%, 20-30 hours per week, salary group E 13 TV-L) based on a fixed-term contract initially limited up to 3 years.

The respective group (https://www.nano.uni-jena.de/) is studying the synthesis, modification and characterization of nano-scale solids, where semiconductor nanowires, metasurfaces and photonic integrated circuits (PICs) are in focus. A variety of different ion beam techniques are used for these proposes, especially to manipulate the optical properties of materials or to analyse them.

Your responsibilities:

We invite applications for PhD projects focused on cutting-edge research in the optical properties of nanowires and ion modified materials. Depending on your academic background and interests, the project may explore:

• Hybridization of lasing nanowires with 2D-materials and dye molecules
• Coupling of lasing nanowires to metasurfaces
• Ion beam modification of phase change materials for metasurfaces
• Ion beam doping of photonic integrated circuits
• SmartCut of optical materials

Your profile:

• You hold a Master's degree (or equivalent) in physics or materials science
• You have strong communication skills in English, both written and spoken
• You are eager to work in an interdisciplinary, dynamic, and international team

Are you hesitating because you don't meet one or some of our requirements? Please do not hesitate to apply and give us a chance to get to know you.
