Nanoscale Transport Phenomena


Nanoscale Transport Phenomena

Erbe, A.; Gemming, S.

The miniaturization and concurrent diversification of functional devices is one of the key technology drivers in science and technology. Following the ITRS roadmap the length scales of functional elements have shrunk to the nanoscale, permitting comparison between controlled experiments and a realistic, scale-adapted modeling of their physical properties.
In this presentation we show studies of transport properties in nanoscale systems, such as electrical current transport through single molecules, magnetic nanoparticles, and nanowires in experiment and simulation. Our results open possible routes towards new functional devices on the molecular and nanometer scale using effects like light-induced switching of single molecules or charging of single electrons to magnetic single electron transistors. Future integration of these nanostructures into micronsize electrical circuits requires structuring techniques, which form contacts by using combinations of self-assembly and top-down approaches. We demonstrate charge transport through self-organized structures and their placement on large electrodes.
