Doctorate Programmes in Nanotechnology and Advanced Materials Science

PhD position Experimental Physics, Optics, Optoelectronics

 The Institute of Physics of the University of Oldenburg, division “Energy and Semiconductor Research Laboratory” in cooperation with the “Ultra-Fast Nano-Optics” group, is offering a
PhD position (23 months Georg-Lichtenberg scholarship, 13 months E13 TV-L 50%)
for in total 3 years at the earliest possible date, preferably not later than 1st of August 2016.
The project “Chiro-Optical Organic Photodetectors” is integrated into the Research Training Group “Nano-Energy-Research”. Information about the program you can find here: https://www.uni-oldenburg.de/en/nanoenergy/.


The PhD project aims at facilitating and characterizing photodetectors, which are sensitive to the circular polarization state of light. The photodetectors use the intrinsic circular dichroism of homo-chiral organic semiconductors implemented as photoactive layer. This novel concept allows polarization resolved conversion of light into photocurrent combined in a single device. This allows for higher information density and leaner devices for optical communication technologies. The unique photoactive materials are provided by an external cooperation partner.
Your tasks are the processing of the photodetectors and their electro-optical characterization, especially the polarization-resolved photocurrent response, by means of spatially and temporally resolved spectroscopy methods. Your emphasis is on fundamental understanding of opto-electronic processes within the photoactive layer. Furthermore, you will conduct optical measurements on plasmonic, circular-dichroic metamaterials for comparison. These samples are provided by another external cooperation partner.


The requirements for hiring are an academic degree (Master or Diploma) in Experimental Physics or an equivalent discipline. Experimental experience within at least one of the following fields is expected: organic semiconductors; photodiodes/photodetectors; transient recordings; ellipsometry; polarization-resolved spectroscopy (such as CD-spectroscopy); X-ray/electron diffraction.


Furthermore, you have the following skills: exceptional motivation; curiosity for basic research questions; experimental skills with passion for detail and an eye for the essentials; willingness to be responsible for experimental setups in the lab; team spirit; advanced English skills.
We offer you: a research training program including funding for conference travel; broad-ranging, interdisciplinary work environment with good infrastructure; access to comprehensive, state-of-the-art lab equipment plus central facility instrumentation; pleasant working atmosphere with flat hierarchy; intensive scientific supervision by a young team.


Send your application no later than the 30th of April 2016 including the following documents: letter of motivation (max 1 page), CV, copies of certificates, summary of your master/diploma thesis (max ½ page) in English. Send your application in a single pdf-file to: chiroptic@uni-oldenburg.de.
