Most types of molecular wires are derived from organic molecules. One naturally occurring molecular wire is DNA.Prominent inorganic examples include polymeric materials such as Li 2 Mo 6 Se 6 [1] and Mo 6 S 9−x I x, [2] [3] [4] [Pd 4 (CO) 4 (OAc) 4 Pd(acac) 2], [5] and single-molecule extended metal atom chains (EMACs) which comprise strings of transition metal atoms directly bonded to each ...
Examples of nanowires include inorganic molecular nanowires (Mo 6 S 9−x I x, Li 2 Mo 6 Se 6), which can have a diameter of 0.9 nm and be hundreds of micrometers long. Other important examples are based on semiconductors such as InP, Si, GaN, etc., dielectrics (e.g. SiO 2 ,TiO 2 ), or metals (e.g. Ni, Pt).
Nanowires are artificial nano- or micro-sized "needles" that can provide high-fidelity electrophysiological recordings if used as microscopic electrodes for neuronal recordings. Nanowires are an attractive as they are highly functional structures that offer unique electronic properties that are affected by biological/chemical species adsorbed ...
Some of these candidates include: hybrid molecular/semiconductor electronics, one-dimensional nanotubes/nanowires (e.g. silicon nanowires or carbon nanotubes) or advanced molecular electronics. Nanoelectronic devices have critical dimensions with a size range between 1 nm and 100 nm. [1]
Another group of nano-technological techniques include those used for fabrication of nanotubes and nanowires, those used in semiconductor fabrication such as deep ultraviolet lithography, electron beam lithography, focused ion beam machining, nanoimprint lithography, atomic layer deposition, and molecular vapor deposition, and further including ...
Until a few years ago, transistors and nanowires were put together to produce the circuit. However, scientists have been able to produce a nanowire with transistors in it. In 2004, Harvard University nanotech pioneer Charles Lieber and his team have made a nanowire—10,000 times thinner than a sheet of paper—that contains a string of ...
Crystal structure of a hexa-tert-butyl-hexa-peri-hexabenzocoronene reported by Müllen and coworkers in Chem. Eur. J., 2000, pp. 1834–1839. Supramolecular electronics is the experimental field of supramolecular chemistry that bridges the gap between molecular electronics and bulk plastics in the construction of electronic circuitry at the nanoscale.

One-dimensional crystalline nanowires are then grown by a liquid metal-alloy droplet-catalyzed chemical or physical vapor deposition process, which takes place in a vacuum deposition system. Au-Si droplets on the surface of the substrate act to lower the activation energy of normal vapor-solid growth.
