The use of single molecules in electronics represents the next limit of miniaturisation of electronic devices, which would enable us to continue the trend of aggressive downscaling of silicon-based electronic devices. More significantly, the fabrication, understanding and control of fully functional circuits at the single-molecule level could also open up the possibility of using molecules as devices with novel, not-foreseen functionalities beyond complementary metal-oxide semiconductor technology (CMOS). This review aims at highlighting the chemical design and synthesis of single molecule devices as well as their electrical and structural characterization, including a historical overview and the developments during the last 5 years. We discuss experimental techniques for fabrication of single-molecule junctions, the potential application of single-molecule junctions as molecular switches, and general physical phenomena in single-molecule electronic devices.

“…Moreover, the frequency dependence of DEP, which gives rise to other processes such as electro-osmotic and electro-thermal flows, has been shown to affect the deposition of NPs between the electrodes [24][25][26]. Such advances in DEP resulted in the successful bridging of NPs in the electrodes gap [27][28][29].…”

Gold nanorods (AuNRs) have attracted great interest due to their excellent plasmonic properties which makes them a promising candidate for many applications. However, most of the applications require control over the position and concentration of nanorods (NRs) by processes that are fast, reliable and scalable. The focus of this work is to study the effects of variation of various parameters, such as applied voltage, frequency, solvents and drying time on the concentration of dielectrophoresis (DEP) -assisted deposition of AuNRs. We have seen that the concentration of AuNRs within the electrodes can be considerably increased by increasing the applied voltage and deposition time, and by choosing a more volatile solvent. Furthermore, the applied frequency also strongly influences the deposition of AuNRs. At lower frequencies, the electro-osmotic flows drag AuNRs to the top of electrodes, while at higher frequencies NRs are deposited close to the electrode edge where the electric field and the field gradient are maximum. We have also carried out simulations using the finite element method to generate the electric field patterns for coplanar electrodes. Our results provide insight into ways in which the concentration of AuNRs can be controlled during DEP-assisted deposition.
