Single?Molecule Doping: Conductance Changed By Transition Metal Centers in Salen Molecules

The creation of molecular components for use as electronic devices has made enormous progress. In order to advance the field further toward realistic concepts, methods controlled modification conducting properties molecules contacted by metallic electrodes need be developed. Here a comprehensive study charge transport in class that allows modifications introducing metal centers into organic structures is presented. Single are electrically and characterized understand role conductance mechanism through junctions. It shown presence single ions modifies energy levels coupling electrical contacts, these lead systematic variations statistical behavior A rigorous analysis thousands junctions performed reveal this correlation. understanding ion resulting an essential step development circuits.
