One-dimensional molecular self-assembly on vicinal surfaces (MOL-VIC)

Molecular structures in the nanometer range exhibit an enormous potential for applications in future electronic data storage and processing devices. Such structures are particularly interesting when created through the process of self-assembly on suitable substrates. Vicinal surfaces are ideally suited as patterned templates for the mass fabrication of one-dimensional structures on the nanometer scale, where conventional lithographic techniques are no longer feasible or affordable. Vicinal surfaces display a two-fold symmetric morphology and, consequently, a complete anisotropy of all physical properties that is retained upon atom or molecule adsorption and thin-film growth. Furthermore, one-dimensional patterns of steps, facets and atomic rows with periodicities on a scale of 1 nm to 100 nm can be produced. We will utilize this unique opportunity to prepare templates for parallel molecular assembly of periodic structures. We combine the expertise of participating groups in nanostructured template preparation, molecule synthesis and assembly on surfaces, in-situ molecule manipulation and spectroscopy, electronic structure characterization, and theoretical calculations to provide the scientific basis for the production of customized molecular assemblies.
