“…Aumolecule-Au junctions have additionally been formed from assemblies of OAE or OAE-like molecules bearing a terminal alkyne-Au complex. 192,193 After self-assembly or LB film transfer onto a gold substrate (using a conventional anchoring group), thermally-induced decomposition of the Au complex results in the loss of ancillary ligands, a reduction from Au(I) to Au(0) and the formation of Au nanoparticles (NPs) on top of the molecular monolayer. The conductance of the resulting Au-[molecule] x -Au NP junctions, containing one or more molecular wires, can be investigated by contacting the NPs with a c-AFM tip.…”

“…Charge transport through single or self-assembled monolayer (SAM) of molecules has attracted great interest in the past two decades [1][2][3][4][5][6][7][8] due to the potential applications of molecular tunnel junctions beyond current scaling limits as diodes, [9][10][11][12] switches, [13][14][15][16] and transistors. 17,18 Furthermore, charge tunneling transport underpins basic physical and chemical mechanisms at the molecular level, such as room-temperature quantum interference (QI) effects, [19][20][21][22] thermoelectricity, 23,24 and dynamic chemical processes.…”

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.

“…Other radical different alternatives to fabricate "soft" top-contact electrodes have been developed recently. Examples include the so-called Thermal Induced Decomposition of an Organometallic Compound (TIDOC) method in which an organometallic film is thermally decomposed-resulting in the formation in situ of gold nanoislands on top of the film without producing short-circuits by penetration of the metal top-contact electrode through the layer [137,138]. Moreover, the fabrication of nanotrenches of controlled width by means of the shadow edge evaporation method resulting in molecular junctions with very good stability and reproducibility, which offer the advantages of large scale integration, reduced leakage currents, and easier access to the molecular layer with external tools [335].…”

The societal impact of the electronics industry is enormous—not to mention how this industry impinges on the global economy. The foreseen limits of the current technology—technical, economic, and sustainability issues—open the door to the search for successor technologies. In this context, molecular electronics has emerged as a promising candidate that, at least in the short-term, will not likely replace our silicon-based electronics, but improve its performance through a nascent hybrid technology. Such technology will take advantage of both the small dimensions of the molecules and new functionalities resulting from the quantum effects that govern the properties at the molecular scale. An optimization of interface engineering and integration of molecules to form densely integrated individually addressable arrays of molecules are two crucial aspects in the molecular electronics field. These challenges should be met to establish the bridge between organic functional materials and hard electronics required for the incorporation of such hybrid technology in the market. In this review, the most advanced methods for fabricating large-area molecular electronic devices are presented, highlighting their advantages and limitations. Special emphasis is focused on bottom-up methodologies for the fabrication of well-ordered and tightly-packed monolayers onto the bottom electrode, followed by a description of the top-contact deposition methods so far used.
