Interface dipole formation in organic surface functionalizations : tailoring metal contacts for organic optoelectronic devices

TL;DRAbstract

This study shows a clear pathway for a successful engineering of metal-organic contacts in organic electronics. Therefore thiolate-based self-assembled monolayers (SAM) were investigated with a dedicated set of experimental methods (Photoemission Spectroscopy and Fourier Transform Infrared Spectroscopy). The analysis of the sample structures requires the decisive infrastructure of an ultra-high vacuum system. Besides the work at the facilities at the National Institute of Standards and Technology (NIST) in Gaitherburg, MD, USA, a new setup was installed at the I. Institute of Physics (IA) at the RWTH Aachen University in Aachen, Germany, during the course of this work. The interpretation of the findings was derived by density functional theory calculations. I particular the detailed modeling of the interfacial region leads to a comparative experimental and theoretical study. Following the previously formulated task of molecular engineering the coupling between gold surfaces and thiolat
