Electron tunneling through self-assembled monolayers of alkanethiols is investigated. Temperature-dependent current– voltage measurements are performed to distinguish between di erent conduction mechanisms. Temperature-independent electron transport is observed, proving direct tunneling as the dominant conduction mechanism of alkanethiols. An exponential dependence of tunneling current on molec...

The field of self-assembled monolayers (SAMs) has witnessed tremendous growth in synthetic sophistication and depth of characterization over the past 15 years.1 However, it is interesting to comment on the modest beginning and on important milestones. The field really began much earlier than is now recognized. In 1946 Zisman published the preparation of a monomolecular layer by adsorption (self...

A review on the mechanisms and characterization methods of electronic transport through self-assembled monolayers (SAMs) is presented. Using SAMs of alkanethiols in a nanometre scale device structure, tunnelling is unambiguously demonstrated as the main intrinsic conduction mechanism for defect-free large bandgap SAMs, exhibiting well-known temperature and length dependences. Inelastic electron...

and Introduction: Ink-jet printing allows for cost efficient roll-to-roll manufacture of thin-film transistors (TFTs) over large areas, enabling next-generation transparent displays, touch panels, opto-electronics, and radio frequency identification [1-4]. TFT conductance and cutoff frequency scale inversely with gate length. However sub-micron gate lengths are incompatible with traditional pri...

Synthesis of the terminally disubstituted rigid rod molecules, [n]staffane-3,3("')-dithiols, n = 1-4, and their singly functionalized derivatives carrying an acetyl or a pentaammineruthenium(II), [ R u ( N H ~ ) ~ ] ~ + , substituent is described. Self-assembled monolayers of the neat [nlstaffane derivatives and of their mixtures with n-alkyl thiols were prepared on polycrystalline gold electro...

We have studied the formation of self-assembled monolayers (SAMs) of n-alkanethiols on platinum thin films using X-ray photoelectron spectroscopy (XPS), reflection-absorption infrared spectroscopy (RAIRS), spectroscopic ellipsometry (SE), and contact angle (CA) measurements. Specifically, SAMs of 1-hexanethiol, 1-dodecanethiol, and 1-octadecanethiol were grown on polycrystalline Pt films, and t...
