Nanowires charge transport

The semiconductor structure is crucial for both electron injection and charge transport after the exciton separation. Meng et al. [35] published a theoretical study focused on the electron injection mechanism in dyad anthocyanine-Ti02 nanowires.

Ohm s law holds for macroscopic samples of an electric conductor. It states that voltage and current are proportional (with the ohmic resistance as proportionaUty factor). The electric resistance itself for a macroscopic wire depends on length and cross-sectional area of the object. Yet these conditions are no longer effective for a nanoscale conductor. The resistance of such a nanowire is independent of its length because charge transport is achieved by so-caUed conduction channels. 

Recently, there have been some attempts to prepare PPV nanowires and nanotubes by electrospinning [380-382]. Electrospim nanofiber consisted of a binary blend of poly[2-methoxy-5-(2-ethylhexyloxy)-p-phenylenevinylene] (MEH-PPV) with regioregular P3HT or poly(9,9-dioctylfluorene) [380]. The resultant nanofiber was found to have the diameter of ca. 100-500 nm with tunable optical and charge transport properties. In this manner, electro-spiiming has been a powerful technique to fabricate polymer, ceramic and inorganic nanowire. Nanotubular structiu e and coaxial nanowire composite could be also fabricated with blend of soluble core and insoluble wall material by the electrospinning method. 

The charge transport in P3AT nanowires synthesized via self-assembly has been studied by fabricating and testing OTFT devices constructed from a single nanowire, or a network of nanowires [79, 80]. A field-effect mobility of 0.02 cm s ... 

From morphological point of view, P3BT usually adopts nanowire-like appearance with a width of 15 nm and a thickness of 5 nm. The variation of these two-dimensional parameters is usually very limited and insensitive to crystallization conditions [9, 11, 24]. So during charge transport along nanowire...

One-dimensional (ID) nanostructures have also been the focus of extensive studies because of their unique physical properties and potential to revolutionize broad areas of nanotechnology. First, ID nanostructures represent the smallest dimension structure that can efficiently transport electrical carriers and, thus, are ideally suited for the ubiquitous task of moving and routing charges (information) in nanoscale electronics and optoelectronics. Second, ID nanostructures can also exhibit a critical device function and thus can be exploited as both the wiring and device elements in architectures for functional nanosystems.20 In this regard, two material classes, carbon nanotubes2131 and semiconductor nanowires,32"42 have shown particular promise.
