Single-molecule electronics: Conductance mechanisms (Physikalisch-chemisches Kolloquium)


invito di Marcus Elstner | guest talk
Hosted by: Technischen Universität Carolo-Wilhelmina zu Braunschweig, Braunschweig, Germany, Physikalische und Theoretische Chemie

Since few years, several quantum transport experiments employing unimolecular systems have been proven. Some of related emerging phenomena, however, are still missing sound theoretical explanations. Principal limitations include the nature of the molecule-to-electrode contacts as well as the commonly used `static' description of molecular bridges. Molecules, indeed, are flexible objects and their nuclear `dynamics' plays in general a fundamental role in charge transfer as well as transport mechanisms. In this talk, I will give an overview on the role of contacts, vibrations and inelastic transport in molecular systems, and show how such phenomena do dramatically affect the overall conduction properties of molecular junctions.
