Energie- und Halbleiterforschung (EHF)



Es geht voran mit den zirkulardichroitischen Photodetektoren ... siehe aktuelle Publikationen.

Interessiert ??? Themen für Masterarbeiten im Bereich Organische Solarzellen und Organische Photodetektoren sind aktuell verfügbar. Details auf Anfrage.


The research of the OEO group is devoted to small molecular organic semiconductors

in nature-inspired and nature-mimicking light sensor,

as well as fundamental investigation of their thin film properties and interface phenomena.

Organic Photodetectors (OPD) from homochiral materials are sensitive to the circular polarization state of light. They allow for polarization based information encoding in optical communication technologies.

Artificial Organic Photoreceptors (AOPR) are, via photoexcitation and capacitive coupling, able to electrically stimulate neuronal cells. They are envisioned as retinal implants for Vision restoration.


If you are interested in curiosity driven research and want to dedicate your experimental Bachelor or Master Thesis in Physics, Engineering Physics or (Physical) Chemistry to organic semiconductors, you can contact me to hear about current project options:
