Electroluminescence from ZnO nanowires with a p-ZnO film/n-ZnO nanowire homojunction

Applied Physics B, 2008
ZnO homojunction light-emitting diodes based on ZnO nanowires were fabricated on Si(100) substrates. An N–In codoped p-type ZnO film grown by ultrasonic spray pyrolysis and an unintentionally doped n-type ZnO nanowire quasi-array grown by an easy low-temperature hydrothermal method were employed to form the homojunction diode.

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°.

Photoluminescence from ZnO nanowires

Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures Processing, Measurement, and Phenomena, 2009
Self-organized ZnO nanowires were grown by metal-organic chemical vapor deposition on sapphire substrate. Steady-state photoluminescence (PL) from the samples with different densities of the nanowires was studied in wide range of temperatures and excitation intensities.

Single-ZnO-Nanowire Memory

IEEE Transactions on Electron Devices, 2011
Single-ZnO-nanowire (NW) memory based on resistive switching is demonstrated for the first time. The NW memory is stable, rewritable, and nonvolatile with on/off ratio up to 7.7 × 105. The O vacancies at the surfaces of ZnO NWs and around the interface of Ti/ZnO NWs observed using X-ray phototelectron spectroscopy, transmission electron microscopy (TEM)

Silica-coated ZnO nanowires

Vacuum, 2012
Abstract ZnO-core/SiO x shell nanowires were successfully fabricated and their morphology, structure, Raman and photoluminescence properties were examined. Not only the sputter-coated product had an one-dimensional morphology, but the tubular structure of SiO x shell was also continuous, smooth, and uniform, along the core nanowires.

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 ...

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

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 ...

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.

DNA - Directed Synthesis of ZnO Nanowires

MRS Proceedings, 2008
AbstractIn this paper, a new and simple method for the synthesis of ZnO nanowires under very mild conditions is presented. The nanowire preparation is based on mineralization from alkaline aqueous zinc nitrate solution in the presence of fish sperm DNA as a structure-directing agent.
