Parallel nano assembling directed by short-range field forces (PARNASS) - Publishable Executive Summary

Project ID: 17071
Funded under: FP6-IST


The PARNASS project is intended to bridge the gap between nanoscience and technology by taking recent advances in the underlying physics and chemistry of nanoscale structures and transferring them to the real world of manufacturing engineering and mass production.
Nanoscale structures are usually manufactured either by chemical processes, e.g. by gas phase deposition, by ion or electron beam supported patterning or by the systematic manipulation of individual objects with scanning probe microscopes. The products of chemical processes always exhibit a stochastic distribution, making them suitable for many applications and even advantageous, e.g. nanoscale surface coatings. However, this method cannot be used to manufacture more complex structures consisting of several elements in a functional arrangement. To a certain extent, the latter two methods mentioned can do so but a serial approach is highly ineffective and relatively unsuited for a production process.
Self organization concepts represent one method to effectively manufacture complex nanostructures. In principle, just as gravitation or spring force are expediently used for macroscopic assembly tasks, forces acting on a scale of a few nanometers can be taken advantage of to support assembly operations. On a scale up to approximately 100 nm, electromagnetic fields and thermodynamic effects cause different types of forces to act between objects of the same order of magnitude. The range and effect of these forces differ fundamentally from the known macroscopic effects and their nature and interaction have scarcely been researched so far.
