In a collaboration with the Laboratoire d'Electronique Moléculaire, CEA Saclay, the controlled stability of molecular junctions has been studied. The work is presented on the cover of Angewandte Chemie International Edition, issue 44/2009O.The original paper: D. Dulic, F. Pump, S. Campidelli, P. Lavie, G. Cuniberti, and A.

Abstract:

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 conductance G, in contrast to the T3 molecule.
