Contacting organic molecules using micro transfer printing — •Stefan Baechle, Artur Erbe, and Elke Scheer — Universität Konstanz, FB Physik, Germany

The formation of metal molecule contacts is one of the main challenges in the fabrication of electronic devices based on the functionality of single molecules. A variety of techniques has already been demonstrated. Most of these processes rely on evaporation of metals or self-organisation of molecules on metals. It has proven to be difficult to separate artifacts from the contacting technique from molecular properties. Therefore contacting techniques, which rely on completely different mechanisms for the formation of the metal molecule contact, are of great importance. Here we demonstrate the fabrication of micron sized contacts using micro transfer printing. The dependence of the conductivity on the area of the contact is studied in order to understand the quality of the contact to individual molecules.
