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
Excited-State Charge Transfer Enabling MoS2/Phthalocyanine Photodetectors with Extended Spectral Sensitivity


The authors of this CRC 951 research highlight demonstrate that excited-state charge transfer from a H2Pc layer enhances the photo response of a monolayer MoS2 without loss in sensitivity extended to spectral regions where the monolayer MoS2 is transparent.

Demonstration of the key substrate-dependent charge transfer mechanisms between monolayer MoS2 and molecular dopants


The authors of this CRC 951 research highlight demonstrate that the charge transfer (CT) mechanism between two-dimensional transition metal dichalcogenide (TMDC) semiconductors and molecular dopant depends critically on the electrical nature of the substrate as well as its electronic coupling with the TMDC.

Gap states induce soft Fermi level pinning upon charge transfer at ZnO/molecular acceptor interfaces


The authors of this CRC 951 research highlight elucidate the origin of limited upward band bending by revealing a notable gap state density-of-states (GDOS)
using high-sensitivity photoemission spectros­copy. Upon acceptor-induced upward band bending, the GDOS with a wide energy distribution becomes increasingly unoccupied.
