Materials Development for Molecular Devices
Mark Rümmeli, IFW Dresden The molecular nanostructures group of the IFW and the chair for Materials Science and Nanotechnology of the Technical University Dresden have developed, over the years, a strong and produtive collaboration. Indeed, so fruitful, mutually supportive and unique is this relationship it is, in practice, more appropriate to term our collaboration a partnership.
In this partnership, we share laboratories and personnel. For example, the molecular nanostructures group at the IFW runs a laser ablation laboratory at the technical university and is currently establishing a second laboratory in partnership with the chair of Prof. Cuniberti. In addition, we share personnel. For example, Imad Ibrahim, a PhD candidate of Prof. Cuniberti is based in our institute working with us to develop molecular junctions in single walled carbon nanotubes as a means to tailor their electronic properties. Moreover, various theoretitians under Prof. Cuniberti are developing theoretical models to better understand such molecular junctions.
Our partnership also includes developing Si nanowires and novel strategies for graphene synthesis and engineering from both an applied and theoretical perspective.
Our interest in Si nanowires lies in their exciting potential as building blocks for bio-sensors and enhanced thermoelectric elements which could form, for example, efficient peltier devices.
Graphene holds massive promise in a variety of areas, including the potential to serve as a key material for future molecular electronics devices. An important area in this sense is their controlled synthesis which an understanding up the underlying growth mechanisms. Together we are building new strategies for novel and exciting formation routes for graphene on oxides.
Artur Erbe The nanotransport group at the Helmholtz-Zentrum Dresden - Rossendorf investigates electronic transport through nanoscale object. In this framework, we collaborate closely with the chair for Materials Science and Nanotechnology of the TUD on understanding current transport through single molecules and DNA strands. In a common lab located at the Hallwachstrasse, we investigate transport properties of single molecules in liquid environments using the mechanically controllable break junction technique.
One highlight of our collaboration is the recent foundation of the international Helmholtz research school NanoNet, an interdisciplinary research school in the field of molecular electronics open to outstanding students of all nationalities with backgrounds in physics, chemistry, electrical engineering, and materials science. The 3-years PhD programme includes independent research work in a project involving different branches of science and engineering and a well-structured scientific curriculum providing for a comprehensive training in technical and professional skills. The research school NanoNet is an initiative of the Helmholtz-Zentrum Dresden-Rossendorf in a joint collaboration with the Technische Universität Dresden, Leibniz Institute of Polymer Research Dresden, Fraunhofer Institute for Nondestructive Testing, and the Nanoelectronics Materials Laboratory gGmbH, and is funded by the Initiative and Networking Fund of the Helmholtz Association.
