Abstract:

Here, we propose a new concept for the fabrication of chemical nanostructures of multifunctional self-assembled monolayers (NanoMuSe) based on metal structures, fabricated by conventional lithographic techniques, that serve as replaceable barrier nanostructures for the self-assembly process. This approach implies a careful engineering of interfacial energies in several transfer processes to maintain the processability of the substrates during the sequence of modification steps. These modification steps include the functionalization of the substrate with different self-assembled monolayers (SAMs), the introduction of chemical functionality to the different surface areas, and cleaning steps. In addition, the employed SAMs require a good stability, as they are subjected to chemical and mechanical treatments that are necessary to remove the barrier structures. Monolayers, which are covalently anchored onto the substrate, can provide this stability. Trichlorosilanes were chosen because it is well-known that they form layers of high quality and stability.
