Hybrid molecular graphene transistor as an operando and optoelectronic platform

Experimental design

We first explore the use of graphene as a high-performance top contact electrode on a single junction showing that: (1) electron transfer between the Fc group in the Au/SC₁₁Fc SAM and the gold electrode is achieved by applying an electrochemical voltage and consequently generating the electrochemical double layer through a Gr monolayer that adjusts the energy level of the system; (2) surface spectroscopy shows that Gr encapsulates the molecules avoiding ambient Fc oxidation and (3) operando examination helps to discuss the transport mechanism in the molecular junction….
