Self-assembly of organic molecules could be a feasible bottom-up
approach to build nanostructures suitable for future electronic devices. In
this thesis, we studied self-assembled structures on metal surfaces as well
as on graphene. We addressed two research questions. On a fundamental
level, we studied the driving mechanisms of a self-assembly structure
(Chapter 4) as well as the subtle, yet peculiar, influence of graphene on
the final nanostructure (Chapter 5). Bridging towards a possible
application, we explored a model systems of self-assembled charge-transfer
complexes (Chapter 6) and established the feasibility of graphene based
organic electronic devices (Chapter 7).
We probed the structural properties of our systems using scanning
tunneling microscopy (STM) on the nanoscale and low-energy electron
diffraction (LEED) on the larger-scale. In one instance, we also studied the
chemical environment of our adsorbents using X-ray photoelectron
spectroscopy (XPS). The electronic properties were explored using
scanning tunneling spectroscopy (STS), ultraviolet photoelectron
spectroscopy (UPS), and angle-resolved photoelectron spectroscopy
