NANOSCALE CONTROL OF THE SPATIAL DISTRIBUTION, SHAPE AND SIZE OF THIN FILMS OF CONJUGATED ORGANIC MOLECULES THROUGH THE PRODUCTION OF SILICON OXIDE NANOSTRUCTURES

摘要

The invention relates to a method of controlling the spatial distribution, shape and size of films of conjugated organic molecules. The inventive method can be used to grow single layers of organic molecules on silicon oxide nanostructures. The silicon oxide nanostructures are produced using an anodic oxidation process. The organisation of the molecules on the oxide nanostructures is dependent on the kinetic parameters of the latter (evaporation rate, diffusion coefficient) and on the interactions with the silicon (anodic) oxide regions. The molecules form domains which exactly reproduce the lateral size and the shape of the oxide nanostructures. The invention provides a powerful method of performing a bottom-up construction of wires, electrodes and charge transfer zones in nanoscale devices.
