Abstract
The electrical transport properties of dodecanethiol (DT) and 2.5"-bis(acet ylthio)-5.2'5'.2" -terthienyl (T3) embedded in metal-molecule-metal junctio ns are investigated. Scannning tunelling microscopy imaging and I-V curves recorded on mechanically breakable junctions allow us to observe a marked d ifference in the electrical behaviour of these molecules: in particular, st eps have been observed in the I-V characteristics of gold-T3-gold junctions , which are not found in the gold-DT-gold ones.
