Abstract: The structural and electronic properties of the organic-organic (donor/acceptor) and organic-metal interfaces are of vital importance for the efficient operation of electronic devices based on organic materials. One of the challenges is to know the molecular-scale details of the interfaces that influence the electronic properties of the system, as modifying the surface work function or favouring the charge transfer at both interfaces. This knowledge is crucial for optimizing devices with efficient charge transport to the electrodes and subsequent charge collection.

For this reason, it is necessary to use experimental methodologies such as combined STM/FM-AFM microscopy in UHV and complemented by XPS/UPS and NEXAFS spectroscopy measurements, which allow investigating, on a molecular scale, the degree of involvement of chemical and structural factors in the generation of electric charge and in the collection processes in the electrodes.

This PhD Thesis Defense will be held in Spanish.
