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
Temperature-Dependent Electronic Ground-State Charge Transfer in van der Waals Heterostructures

 

The authors of this CRC 951 research highlight experimentally observed that the amount of ground-state charge transfer in a van der Waals (vdW) heterostructure increases by a factor of 3 when going from 7 K to room temperature. State-of-the-art electronic structure calculations of the full heterostructure reveal intracomponent electron–phonon coupling and inter-component electronic coupling as the key factors determining the amount of charge transfer.

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.
