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 third funding period (2019-2023).

Recent Research Highlights
Direct observation of state-filling at hybrid tin oxide/organic interfaces


Electroluminescence (EL) spectra of hybrid charge transfer states at metal oxide/organic type-II heterojunctions exhibit bias-induced spectral shifts. The authors of this CRC 951 research highlight combine the results of EL and photovoltaic measurements to eliminate the unavoidable effect of the series resistance of inorganic and organic components on the total voltage drop across the hybrid device.

Pulsed thermal deposition of binary and ternary transition metal dichalcogenide monolayers and heterostructures


The authors of this CRC 951 research highlight present a facile pulsed thermal deposition method which provides precise control over the number of layers and the composition of two-dimensional systems.

Surface termination dependent work function and electronic properties of Ti3C2Tx MXene


The authors of this CRC 951 research highlight investigated the electronic properties of Ti3C2Tx for different surface terminations, as achieved by different annealing temperatures, with the help of photoelectron spectroscopy, inverse photoelectron spectroscopy, and density functional theory calculations.
