Broadband ZnO Single Nanowire Light Emitting Diode [PDF]

open access: yesIntegrated Photonics Research and Applications/Nanophotonics, 2006
We present a novel technique for reliable electrical injection into single semiconductor nanowires for light-emitting diodes and lasers. The method makes use of a high-resolution negative electron-beam resist and direct electron-beam patterning for the precise fabrication of a metallic top contact along the length of the nanowire, while a planar ...

Growth behavior and field emission property of ZnO nanowire arrays on Au and Ag films

open access: yesAIP Advances, 2013
We propose a facile method to control the growth and areal density of zinc-oxide (ZnO) nanowire arrays using gold or silver films deposited on aluminum-doped ZnO (AZO) layers coated on glass substrates. Nanowires exceeding 5 μm in length grew on both the

Coulomb Oscillations of Indium-doped ZnO Nanowire Transistors in a Magnetic Field

open access: yes, 2010
We report on the observation of Coulomb oscillations from localized quantum dots superimposed on the normal hopping current in ZnO nanowire transistors. The Coulomb oscillations can be resolved up to 20 K.

Carbon-assisted nucleation and vertical growth of high-quality ZnO nanowire arrays

open access: yesAIP Advances, 2011
We developed a carbon-assisted physical-vapor-deposition method for the growth of highly aligned ZnO nanowire arrays on any flat substrates in large area. Amorphous carbon (a-C) films acted as the preferential nucleation sites to facilitate the growth of

Detection mechanism in highly sensitive ZnO nanowires network gas sensors

open access: yes, 2019
Metal-oxide nanowires are showing a great interest in the domain of gas sensing due to their large response even at a low temperature, enabling low-power gas sensors.

Nanostructured semiconductor materials for dye-sensitized solar cells [PDF]

open access: yes, 2017
Since O'Regan and Grätzel's first report in 1991, dye-sensitized solar cells (DSSCs) appeared immediately as a promising low-cost photovoltaic technology.

The Realization of ZnO Nanowires Interconnection through Femtosecond Laser Irradiation of Ag Nanoparticles Solder

open access: yesApplied Sciences, 2022
Nanowire interconnection is the basis for the construction and integration of micro-nano functional devices. But so far, it is still difficult to achieve a reliable interconnection of metal oxide nanowires.

Graphene coated ZnO nanowire optical waveguides

open access: yesOptics Express, 2014
We report the fabrication and characterization of freestanding graphene coated ZnO nanowires (GZNs) for optical waveguiding. The GZNs are fabricated using a tape-assist transfer under micromanipulation. Owing to the deep-subwavelength diameter and high index contrast of the ZnO nanowire waveguide, light-graphene interaction is significantly enhanced by

ZnO@TiO2 Core/Shell Nanowire Arrays with Different Thickness of TiO2 Shell for Dye-Sensitized Solar Cells

open access: yesCrystals, 2020
The ZnO@TiO2 core/shell nanowire arrays with different thicknesses of the TiO2 shell were synthesized, through depositing TiO2 on the ZnO nanowire arrays using the pulsed laser deposition process.

Investigating Organic Vapor Sensing Properties of Composite Carbon Nanotube-Zinc Oxide Nanowire

open access: yesChemosensors, 2022
The low operating temperature of nanowire gas sensors along with their high surface-to-volume ratio are two factors that make gas sensors more practical. In this paper, the growth of ZnO nanowires on a vertically aligned CNT forest is reported.
