Abstract
Films of simple organic molecules deposited on metal and semiconductor substrates are of relevant scientific interest for a widely spread series of possible applications, spanning from nanostructured electronic devices to sensors, from photo-voltaic systems to bio catalysts, from lubricants to corrosion control systems etc. The research of the proposed project focuses on studying different heteroepitaxial systems like organic molecular films on metallic substrates as well as ultrathin metallic overlayers of uniform thickness on semiconductor systems where the role of reduced dimensionality, confined film geometry and structural mismatch with the substrate as well as particular bonding strength of the organic molecules within the film has a substantial impact on the film macroscopic properties. Organic thin film properties can in fact be tuned by choosing among the many available organic molecules. These systems presents challenges to the conventional theoretical methods employed to calculate electronic and structural properties of covalent systems. On the experimental side, the complexity of these systems requires a multi-techniques approach, where the combined information on the structure, dynamics, morphology and electronic structure is essential to understand the fundamental physics and chemistry involved in the film formation. The present research program aims at enriching the comprehension of the microscopic mechanisms of interface formation, film growth, charge transport within the film and at the interface, by means of diffraction and spectroscopic experimental techniques available at the ALOISA and HASPES beamlines whereas the spectromicroscopical studies of inhomogeneous interfaces will be studied at the Escamicroscopy beamline, which all exploit the advanced characteristics of 3rd generation synchrotron radiation of the Elettra synchrotron light source. In addition, in house research with nondestructive scattering of thermal He atoms as well as diffraction with low energy electrons available at the TASC/INFM laboratory for surface physics will be used to complement the synchrotron measurements
