Electrowetting on ZnO nanowires

Applied Physics A, 2010
In this paper, we study the electrowetting character on ZnO nanowires. We grow the ZnO nanowires on indium tin oxide (ITO) by a hydrothermal method, and the ZnO nanowires surface is further hydrophobized by spin-coating Teflon. Such a prepared surface shows superhydrophobic properties with an initial contact angle 165°.

Resistive Switching Characteristics of ZnO Nanowires

Journal of Nanoscience and Nanotechnology, 2014
Binary transition metal oxides such as ZnO, TiO2, and MnO; and their various structures such as thin film, nanowire, and nanoparticle assembly; have been widely investigated for use in insulators in resistive random access memory (ReRAM), considered a next-generation nonvolatile memory device. Among the various driving mechanisms of resistive switching

Aligned growth of ZnO nanowires and lasing in single ZnO nanowire optical cavities

Applied Physics B, 2008
Ordered ZnO nanowire arrays have been fabricated in N2 background gas by catalyst-free nanoparticle-assisted pulsed-laser deposition. A single ZnO nanowire was collected in an electrode gap by dielectrophoresis. Under the optical pumping above an exciting laser (λ= 355 nm) threshold of ∼ 334 kW/cm2, ultraviolet lasing action in a single ZnO nanowire ...

Multiphoton route to ZnO nanowire lasers

Optics Letters, 2006
With intense femtosecond laser excitation, multiphoton absorption-induced stimulated emission and laser emission in ZnO bulk crystal and nanowires have been demonstrated at room temperature. UV-stimulated emission peaks appeared in both bulk crystal and nanowires when the excitation exceeded certain thresholds, and a sharp lasing peak with a linewidth ...

Permanent bending and alignment of ZnO nanowires

Nanotechnology, 2011
Ion beams can be used to permanently bend and re-align nanowires after growth. We have irradiated ZnO nanowires with energetic ions, achieving bending and alignment in different directions. Not only the bending of single nanowires is studied in detail, but also the simultaneous alignment of large ensembles of ZnO nanowires.

Structure study of electrodeposited ZnO nanowires

Microelectronics Journal, 2005
Abstract In this work, we report on the structure study of electrodeposited ZnO nanowires. The samples were mounted as a working electrode and the deposition was performed in a classical three electrodes electrochemical cell. For obtaining ZnO nanowires, the working electrode was a polycarbonate membrane with a random distribution of nanometric pores,

Thermal Conductivity of ZnO Single Nanowire

Journal of Nanoscience and Nanotechnology, 2016
The thermal conductivity of a single ZnO nanowire with diameter of ~150 nm was measured using a four-point-probe 3omega method over a temperature range of 140-300 K. The measured ther- mal conductivity of ZnO nanowire is strongly reduced compared to bulk ZnO crystal due to the enhanced phonon-boundary and impurity (isotope) scattering.

A ZnO nanowire vacuum pressure sensor

Nanotechnology, 2008
In this study, we report the growth and characterization of lateral ZnO nanowires (NWs) on ZnO:Ga/glass templates. Using x-ray diffraction and micro-Raman spectroscopy, it was found that crystal quality of the as-grown ZnO NWs is good. It was also found that the average length and average diameter of the laterally grown ZnO NWs were 5 µm and 30 nm ...

ZnO Nanowire-Based UV Photodetector

Journal of Nanoscience and Nanotechnology, 2010
ZnO nanowire-based ultraviolet (UV) photodetector was proposed and fabricated by depositing interdigitated Au film on vertically well aligned ZnO nanowires. It was found that the deposited Au film form good ohmic contact with the underneath ZnO nanowires.
