The CRC 951 - Hybrid Inorganic/Organic Systems for Opto-Electronics (HIOS) - was an interdisciplinary effort bringing together scientists with complementary expertise from four universities and two non-university institutions. The goal was 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 enabled 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 had a duration of three funding periods until June 2023.

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.
