Odd-even effects in charge transport across self-assembled monolayers.
This paper compares charge transport across self-assembled monolayers (SAMs) of n-alkanethiols containing odd and even numbers of methylenes. Ultraflat template-stripped silver (Ag(TS)) surfaces support the SAMs, while top electrodes of eutectic gallium-indium (EGaIn) contact the SAMs to form metal/SAM//oxide/EGaIn junctions. The EGaIn spontaneously reacts with ambient oxygen to form a thin (∼1...
متن کاملCrystallization on Self Assembled Monolayers
Over the past two decades, self assembled monolayers (SAMs) (Love et al., 2005; Smith et al., 2004; Ulman, 1996) have been extensively studied due to their many applications in various fields such as electrochemistry (Eckerman et al., 2010), biosensors (Nyquist et al., 2000), protein separation (Chun and Stroeve, 2002) and enantiomer separation (Mastai, 2009). SAMs are organic assemblies formed...
متن کاملSelf Assembled Monolayers -A Review
Self assembly provides a simple route to organise suitable organic molecules on noble metal surface by using long chain organic molecules with various functionalities like -SH,-COOH,-NH2 , Silanes etc. These surfaces can be used to build up interesting nano level architectures. Self assembly is an interesting process for biological relevance because it provides a novel approach to complex struc...
متن کاملElectronic transport in self-assembled alkanethiol monolayers
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...
متن کاملElectron tunnelling in self-assembled monolayers
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...
