The research of the OEO group is devoted to small molecular organic semiconductors
their structure correlated excitonic properties, especially chirality routed excitonic circular dichroism and spin-polarization, and interface phenomena
as well implementaion into opto-electronic devices.
Excitonic Circular Dichroism (ECD) is an optical property in organic matter arising from the strucutral phenomenon of mirror-symmetry breaking in homochiral supramolecular aggregates. In thin films, it can by probed best by Mueller Matrix Ellipsometry. ECD is not necessarily a tiny quantity in organic matter, in some cases it can be giant.
Organic photodetectors based on homochiral materials are intriniscally sensitive to the circular polarization state of light without the need for polarization manipulating elements. They allow for polarization based information encoding in optical communication technologies.
Transient photovoltaic neuro-stimulating platforms are, via photoexcitation and capacitive coupling, able to electrically stimulate neuronal cells. They are envisioned as minimal invasive, wireless retinal implants for Vision Restoration (see also PRO-RETINA-Stiftung).
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, their circular dichroic properties, their application in opto-electronic devices and/or polarized optical spectroscopy & microscopy, don't hesitate to contact me to hear about current project options:
