Master Thesis: Designed Architectures of Si Nanoparticles on Self‐Assembled Monolayers

There is an increasing interest to fabricate new generation electronic devices, which are based on the quantum properties of nanostructured materials. In particular, nanoparticles are being intensively investigated as ideal building blocks for the new devices, because of their semiconducting properties, nanoscale size and size tunable electronic structure [1].

The aim of this project is to create a stable immobilization and homogenous distribution of these nanostructures on solid substrates, which can allow for device optimization and electrical characterization. Moreover, we are interested in controlling and modifying the positioning of the nanostructures at the nanoscale by using chemically patterned self‐assembled monolayers of organophosphonic acids on the surface as a template for the selective organization of the nanoparticles [2, 3].

Different surface techniques will be employed to characterize the novel functional interfaces generated, such as X‐ray photoelectron spectroscopy, contact angle, atomic force microscopy, electrochemistry, and Raman spectroscopy. Finally, the novel nanodevices fabricated will be characterized with respect to their electronic properties using electrical measurements.
