Nanoparticles with their specific chemical and electrical properties allow the production of new types of electronic devices, catalytic systems or complex functional surface coatings. For many of these applications it is sufficient to deposit the particles randomly or self-assembled. However, a large number of potential applications like quantum dots, single electron transistors, and quantum computers need an exact placement of single nanoparticles with sub-10 nm in resolution and size. Techniques, that provide an exact online-placement of countable nanoparticles for functional electronic devices are still missing. For the solution of this problem a new method called "cluster-jet" is proposed. It is based on a gasphase nanoparticle source connected to a focussing collimator system. The collimator system consists of electromagnetic lenses and a pierced AFM-tip. The objective of this technique is to assemble countable single nanoparticles with a spatial resolution of 10 nm or below to a pre-structured substrate. The method will be used to produce and investigate quantum and electronic device based structures as well as nano particle structures composed of materials with different chemical composition.
