Enhanced Thermoelectric Performance of Rough Silicon Nanowires.
Approximately 90 per cent of the world's power is generated by heat engines that use fossil fuel combustion as a heat source and typically operate at 30-40 per cent efficiency, such that roughly 15… Expand

This work introduces a version of the dye-sensitized cell in which the traditional nanoparticle film is replaced by a dense array of oriented, crystalline ZnO nanowires, which features a surface area up to one-fifth as large as a nanoparticle cell. Expand
One‐Dimensional Nanostructures: Synthesis, Characterization, and Applications
This article provides a comprehensive review of current research activities that concentrate on one-dimensional (1D) nanostructures—wires, rods, belts, and tubes—whose lateral dimensions fall… Expand
Giant piezoresistance effect in silicon nanowires
It is reported that Si nanowires possess an unusually large piezoresistance effect compared with bulk, which may have significant implications in nanowire-based flexible electronics, as well as in nanoelectromechanical systems. Expand
Enhanced thermoelectric performance of rough silicon nanowires
Electrochemical synthesis of large-area, wafer-scale arrays of rough Si nanowires that are 20–300 nm in diameter show promise as high-performance, scalable thermoelectric materials. Expand

Room-Temperature Ultraviolet Nanowire Nanolasers
Room-temperature ultraviolet lasing in semiconductor nanowire arrays has been demonstrated. The self-organized, <0001> oriented zinc oxide nanowires grown on sapphire substrates were synthesized with… Expand
Catalytic Growth of Zinc Oxide Nanowires by Vapor Transport
nanoparticles in dimethylsulfoxide onto the PLL film for about 20 min, after which it was rinsed in dimethylsulfoxide and then dichloromethane. From the molecular weight, the average length of the… Expand
Light trapping in silicon nanowire solar cells.
It is demonstrated that ordered arrays of silicon nanowires increase the path length of incident solar radiation by up to a factor of 73, which is above the randomized scattering (Lambertian) limit and is superior to other light-trapping methods. Expand
Nanowire ultraviolet photodetectors and optical switches
no attention has been given to the photoconducting properties of nanowires despite the exciting possibilities for use in optoelectronic circuits. Here, we show the possibility of creating highly… Expand
