Galvanic nanodots as catalysts for carbon nanotubes

For more than a decade carbon nanotubes (CNTs) are accepted as a very promising material for many applications, including chemical sensors, transistors, and novel electrodes for a variety of molecular devices. The idea, that CNTs might be integrated with conventional microstructures to obtain new types of nanoscale devices, is fascinating, however, it requires an ability to synthesize, isolate, manipulate and connect individual nanotubes at defined positions.
The project is aimed at in-place growth of separated well distributed carbon nanotubes, which can be used for CNT-based devices (electrodes, transistors) or for adhesive layers. First, one has to think how to fix a carbon nanotube at a certain place of the microchip. This can be achieved by fixing or nanopositioning a catalytic particle, serving as a nucleation center to a carbon nanotube. For this purpose nanosized metal dots have to be created by a method called AFM-based nanogalvanization.
