The CRC 951 - Hybrid Inorganic/Organic Systems for Opto-Electronics (HIOS) - is an interdisciplinary effort bringing together scientists with complementary expertise from three universities and two non-university institutions. The goal is the merger of inorganic semiconductors, conjugated organic materials, and metal nanostructures into novel hybrid structures. Elucidating and tailoring the fundamental chemical, electronic, and photonic interactions in these systems will enable us the development of functional elements exhibiting superior opto-electronic functionalities not achievable with any of the individual material classes alone. The CRC 951 was founded in July 2011 and is currently in its second funding period (2015-2019).

Recent Research Highlights
State-of-Matter-Dependent Charge-Transfer Interactions between Planar Molecules for Doping Applications


Controlling the electrical conductivity of organic semiconductors is a key asset for organic electronics, nowadays realized mostly by molecular dopants. Here, the authors study p-type doping of the planar organic semiconductor (DBTTF) in combination with the electron acceptors  (TCNNQ) and (F6TCNNQ) as planar dopants.

Uncovering the (un-)occupied electronic structure of a buried hybrid interface


The energy level alignment at organic/inorganic (o/i) semiconductor interfaces is crucial for any light-emitting or -harvesting functionality. Essential is the access to both occupied and unoccupied electronic states directly at the interface, which is often deeply buried underneath thick organic films and challenging to characterize.
