Unified Density Functional Description of Bonding and Interactions at Inorganic/Organic Interfaces
The accuracy and efficiency of parameter-free density functional methods to describe chemical and physical phenomena in inorganic/organic interfaces has been shown in the first and second periods of the CRC.
The project focusses on interfaces between versatile organic building blocks and semiconducting as well as metallic substrates. We specifically aim at providing insight in interlink chemistry of the second organic layer and predicting new interfaces with interesting electronic properties based on the design principles revealed. Our quantitative energy-based analysis method is now broadly applicable to all kinds of interfaces and will guide our investigations. We use mainly density functional theory complemented by accurate wavefunction based methods.
Connection to experimental projects will be made through the analysis of spectroscopic quantities at the interfaces.
