We will present a recent work where we discuss the range of validity of coherent versus incoherent theory treatments for the understanding of some recent experimental results obtained in molecular tunnel junctions and employ them to determine some noteworthy characteristics of the junctions in view of potential applications in molecular electronics. Specifically, we will discuss single-level transport models employed to explain experiments performed in SAM-based EGaIn junctions of S(CH2)nFcC13-n electrical rectifying molecules in where the Ferrocene (Fc) unit is placed at different positions (n) within the alkyl chain, enabling the determination of the electrostatic potential profile in the junction, which we find highly non-linear.
