Thin metallic nanowires are highly promising candidates for plasmonic waveguides in photonic and electronic devices. We have observed that light from the end of a silver nanowire, following excitation of plasmons at the other end of the wire, is emitted in a cone of angles peaking at nominally 45-60 degrees from the nanowire axis, with virtually no light emitted along the direction of the nanow...

We have studied the adsorption of mercaptopropionic acid, 2,2'-bipyridine, and dopamine onto electrochemically fabricated Cu nanowires. The nanowires are atomically thin with conductance quantized near integer multiples of 2e(2)/h. Upon molecular adsorption, the quantized conductance decreases to a fractional value, due to the scattering of the conduction electrons by the adsorbates. The decrea...

We report one dimensional (1D) MoS2 nanosheet/porous TiO2 nanowire hybrid nanostructures synthesized by a simple hydrothermal method, leading to an enhanced specific surface area (66 m(2) g(-1)). These 1D hybrid nanostructures as co-catalysts exhibit high activity in visible light photocatalytic hydrogen evolution reaction (HER) with an enhanced hydrogen generation rate of 16.7 mmol h(-1) g(-1).

An intriguing formation of nanoscale buckles is discovered when an array of aligned silver nanowires was deposited onto prestrained polydimethylsiloxane substrates. The spacing distance between the resulting silver nanoparticles corresponds to the buckling wavelength of the silver nanowires. The buckled nanowires exhibit unique optical properties, such as interruption of scattered polarized pho...

The thermal conductivities of individual single crystalline intrinsic Si nanowires with diameters of 22, 37, 56, and 115 nm were measured using a microfabricated suspended device over a temperature range of 20–320 K. Although the nanowires had well-defined crystalline order, the thermal conductivity observed was more than two orders of magnitude lower than the bulk value. The strong diameter de...

High quality ZnO nanowires arrays were homoepitaxial grown on Ga-doped ZnO single crystal (GZOSC), which have the advantages of high conductivity, high carrier mobility and high thermal stability. When it was employed as a photoanode in the DSSCs, the cell exhibited a 1.44% power-conversion efficiency under the illumination of one sun (AM 1.5G). The performance is superior to our ZnO nanowires/...

Low-temperature growth of indium tin oxide (ITO) nanowires (NWs) was obtained on catalyst-free amorphous glass substrates at 250 °C by Nd:YAG pulsed-laser deposition. These ITO NWs have branching morphology as grown in Ar ambient. As suggested by scanning electron microscopy (SEM) and high-resolution transmission electron microscopy (HRTEM), our ITO NWs have the tendency to grow vertically outw...

the effect of length variation on the magnetic properties of nife alloy nanowires electrodeposited into the alumina template was investigated. the diameter (45±2.5 nm) and length (~ 1.9, 7.12, 8.3, 9.5 and 13.3 µm) of the nanowires were estimated from scanning electron microscopy images. energy dispersive spectroscopy results showed ni3fe7 composition of the alloy nanowires.  the magnetic prope...

A transparent conducting film composed of regular networks of silver nanowires is obtained by combining a soft solution process (Tollens' reaction) and nanoimprint lithography. The solution-grown nanowire networks show a threefold higher conductivity than grids obtained by metal evaporation. This is due to the larger grain size in the solution-grown nanowires, which results in a strong reductio...
