Structured Graphene are Ideal Electrodes to Tune Single-molecule Conductance

Structured Graphene are Ideal Electrodes to Tune Single-molecule Conductance - Featured

A team formed by Joel G. Fallaque, Sandra Rodríguez-González, Cristina Díaz and Fernando Martín who are IFIMAC, IMDEA, UAM and UCM researchers, has recently shown that structured graphene can be an ideal electrode to modulate the electric currents through single-molecules junction. They have shown that the moiré structure developed by the adsorption of graphene on Ru(0001), that modules it electronic structure, allows one to tune the electronic transport properties of a molecule junction just by changing the anchoring site. The currents through the junction can be varied as much as an order or magnitude. They have also shown that the modulation and polarization strongly depends on the nature of the chemical binding between the molecule and the graphene electrode. [Full article]
