Projecting the nanoworld: Concepts, results and perspectives of molecular electronics

Abstract

A bottom-up approach is a promising alternative to build nanodevices and/or nanomachines starting from molecular building blocks. The idea of molecular electronics comes from a farsighted paper by Aviram and Ratner, predicting that single molecules with a donor-spacer-acceptor structure would have rectifying properties when placed between two electrodes. Today, molecular electronics is emerging as an alternative to Si-nanoelectronics for building integrated devices. This review aims to give an overview of this emerging field, analysing the concepts, the key results and the perspectives.

Carbon Nanotubes – Imprinted Polymers: Hybrid Materials for Analytical Applications

“…The electrical conductivity in CNTspolymer nanocomposites depends on dispersion (Sandler et al, 2003;Li J. et al, 2007b;Song & Youn, 2005), alignment (Choi et al, 2003;Fangming et al, 2003), aspect ratio (Bai & Allaoui, 2003;Bryning et al, 2005), degree of surface modification (Georgakilas et al, 2002) of CNTs, polymer types (Ramasubramaniam et al, 2003) and composite processing methods (Li J. et al, 2007b). Based on their characteristic, CNTs-polymer composites can behave as conductors, semiconductors or insulators (Maruccio et al, 2004).…”

“…Third, the (activated) relaxation of an MSCC-back to a GSCC-dominated distribution is temperature-dependent and so the kinetic parameters may be quantified through time-and temperature-dependent measurements. For example, the DG 298 z for this process in the case 16 17,18 or rectifier, [19][20][21][22][23] or perhaps generates some unusual device characteristic, such as negative differential resistance. 24,25 Such properties are uniquely studied in the device setting and may arise from a distinctly molecular property, or from the result of the molecule/electrode interaction.…”

Investigation of interaction hydrogen sulfide with (5,0) and (5,5) single-wall carbon nanotubes by density functional theory method

“…There is a strong demand for improved sensitivity, selectivity, stability, and low-power consumption beyond what is offered by commercially available sensors. In order to satisfy this demand, nanotechnologies are employed, providing new materials, devices, and systems with structures and components that can exhibit novel and significantly improved physical and chemical properties because of their nanoscale size [16]. The operation at the room temperature with sensitivity as high as 10 3 , besides their small size, is the main advantage of semiconducting-SWCNT sensors.…”
