The CRC 951 - Hybrid Inorganic/Organic Systems for Opto-Electronics (HIOS) - is an interdisciplinary effort bringing together scientists with complementary expertise from four 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 third funding period (2019-2023).

Recent Research Highlights
Type-I Energy Level Alignment at the PTCDA—Monolayer MoS2 Interface Promotes Resonance Energy Transfer and Luminescence Enhancement


The authors of this CRC 951 research highlight demonstrate by direct and inverse photoelectron spectroscopy that the energy level alignment at the interface of PTCDA and monolayer ML-MoS2 corresponds to a type-I heterojunction.

The interlayer method: A universal tool for energy level alignment tuning at inorganic/organic semiconductor heterojunctions


The authors of this CRC 951 research highlight demonstrate a universal approach to adjust the offset between the energy levels at inorganic/organic semiconductor interfaces by inserting a monolayer-thick interlayer comprising strong electron donor or acceptor molecules between the two semiconductors.
