Redox Control of Charge Transport in Vertical Ferrocene Molecular Tunnel Junctions

Abstract

Controlling charge transport through molecular-scale devices is of crucial importance. This article reports an effective route to tailor cross-plane charge transport in a vertical molecular tunneling junction through controlled chemical or electrochemical redox reaction in the self-assembled molecular monolayers buried under graphene. This redox control of the cross-plane charge transport is important for exploring fundamental mechanisms and realizing new functionalities in molecular electronics.
