Elektronentransport durch metallische und organische Drähte

Schematic representation of a single-molecule junction. The central part formed by the molecule plus part of the metallic electrodes constitutes what we call the central cluster. Finally, this cluster is coupled to two semi-infinite leads made of the same metallic material.

Formation of a chain of gold atoms as obtained from a molecular dynamics simulation. The upper panels shows the forces during the breaking of the contact, while the middle panels shows the minimum cross section, total conductance and channel transmissions during the formation of the wire.

Scanning electron micrograph with a SiO2 bridge, covered by a thin gold layer. This setup allows improved access with light and enlarges the experimental potential of the method.
