Collaborative Research Centre 951 - CRC 951
Sonderforschungsbereich 951 - SFB 951
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 June 2011 and is currently in it's second funding period (2015-2019).

Recent Research Highlights
Tuning the work function of GaN with organic molecular acceptors
In this CRC 951 research highlight the capability of two molecular organic acceptors to tune the work function of intrinsically doped GaN(0001) and for comparison of intrinsically doped ZnO(0001) is demonstrated and the fundamental physical phenomena involved are unraveled. The ability to adjust the GaN work function with molecular interlayers at will could lead to a wide manifold of device realizations, e.g., high-frequency and sensor applications or hybrid light-emitting diodes with a wide emission energy range.

Ultrafast Nonlinear Response of Bulk Plasmons in Highly Doped ZnO Layers
Understanding the plasmon dynamics in inorganic systems is vital for the development of hybrid plasmonic systems. In this recent CRC 951 research highlight we present the first ultrafast optical study of longitudinal “bulk” plasmons in a two-layer, highly n-doped ZnO:Ga system.

Topically, HIOS is part of the Integrative Research Institute for the Sciences (IRIS Adlershof) where hybrid systems are one of the strategic focal points. IRIS is also supporting the CRC 951 by providing office space and assistance in the organization of scientific events.
