A surface-adsorbed molecule is contacted with the tip of a scanning tunneling microscope (STM) at a pre-defined atom. On tip retraction, the molecule is peeled off the surface. During this experiment, a two-dimensional differential conductance map is measured on the plane spanned by the bias voltage and the tip-surface distance. The conductance map...
Die Schlusselrolle der Grenzflachen in Elektroden-Molekul-Kontakten kann anhand des zeitlichen Verlaufs der elektrischen Leitfahigkeit durch sie untersucht werden. In der Zuschrift auf S. 8423 ff. zeigen A. Filoramo et al., dass das „Blinken“ der Thiol-Gold-Bindung durch geeignete Wahl des Molekuls unterdruckt werden kann: Bei Kontakten mit dem Ter...
Influence of interfaces on thiol-terminated molecular wires consisting of three phenyl (P3) or three thiophene (T3) rings was monitored by a new statistical approach based on mechanical controllable break junction technique (see SEM image of the junction and schematic of molecular arrangement). The P3 molecule exhibits stochastic variations in cond...

Using a scanning tunneling microscope we have measured the quantum conductance through a PTCDA molecule for different configurations of the tip-molecule-surface junction. A peculiar conductance resonance arises at the Fermi level for certain tip to surface distances. We have relaxed the molecular junction coordinates and calculated transport by mea...
A minimal model for coherent transport through a donor/acceptor molecular junction is presented. The two donor and acceptor sites are described by single levels energetically separated by an intramolecular tunnel barrier. In the limit of strong coupling to the electrodes a current rectification for different bias voltage polarities occurs. Contacts...
