controllable break junctions (MCBJ) technique"

Abstract: 

 

Exploring the possibilities to use individual molecules as building blocks
of molecular devices is one of the most difficult tasks in the field if
molecular electronics. To achieve this it is necessary to measure,
understand and control electron transport through molecules attached to
electrodes.

 

Despite enormous advances in the field in the past ten years, a number of
fundamental questions, such as: "What is the nature of transport through
these systems, and how can we employ and tune their electrical properties
for new electronic devices?" have not been answered yet.

 

The conductance of a molecule depends not only on its intrinsic properties,
but is very sensitive to the atomic level details of the molecule-electrode
contact and the local environment of the molecule. Therefore, the main
question is: "How to reliably connect a nano-object to the macroscopic
world?" 

 

 I will present an overview in the development of the mechanically
controllable break junctions (MCBJ) technique in the past ten years and some
recent advances, such as mechanical and electrostatical (gate) tuning of the
charge transport in a single - porphyrin molecule.
