Focused ion beam (FIB)-induced mixing was studied in a hybrid C/Si/C/Si/C/Si multilayer structure, where amorphous SiC thin film with thickness in the nanometer range was produced. The ion irradiation induced a slightly asymmetric intermixing of the top C and Si layers. During ion mixing, part of the intermixed C and Si atoms reacted, forming amorphous SiC. The amount of SiC depends on the square root of the ion fluence.

Understanding the role of intermolecular interaction on charge transfer characteristics in π-stacked molecular systems is central to the rational design of hybrid electronic materials. However, a quantitative study of charge transfer in such systems is often difficult because of poor control over molecular morphology. Using resonant photoemission spectroscopy we studied the femtosecond charge-transfer dynamics in cyclophanes, which consist of two precisely stacked pi-systems. We attributed difference in charge transfer to the decreased inter-ring electronic coupling.

Within our research with synchrotron radiation performed at the ALOISA beamline of Elettra synchrotron, we investigated the electronic structure of hetero-organic interfaces and hybrid nanostructures. Specifically, we showed that via specific amino/carboxyllic recognition scheme, ultrathin molecular films of cysteammnine effectively bridge and selectively couple further organic layers like that of tetraphthalic and benzoic acid to the metallic substrates. Furthermore we have observed, that amino/carboxylic bonding allows ultrafast charge transfer across the hybrid molecular interface, comparable to that provided by a much stronger covalent bonding between cysteammnine molecules and metallic substrate.
