p-Type ZnO Nanowire Arrays

Nano Letters, 2008
Well-aligned ZnO nanowire (NW) arrays with durable and reproducible p-type conductivity were synthesized on alpha-sapphire substrates by using N2O as a dopant source via vapor-liquid-solid growth. The nitrogen-doped ZnO NWs are single-crystalline and grown predominantly along the [110] direction, in contrast to the [001] direction of undoped ZnO NWs ...

ZnO Spintronics and Nanowire Devices

MRS Proceedings, 2004
ABSTRACTZnO is a very promising material for spintronics applications, with many groups reporting room temperature ferromagnetism in films doped with transition metals during growth or by ion implantation. In films doped with Mn during PLD, we find an inverse correlation between magnetization and electron density as controlled by Sn doping.

Chemical Sensing with ZnO Nanowire

IEEE Sensors, 2005., 2005
Zinc oxide nanowires were configured as n-channel field effect transistors. These transistors were implemented as chemical sensors for detection of various gases. Nanowire's ammonia sensing behavior was observed to switch from oxidizing to reducing when temperature increased from 300 to 500 K.

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.

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 ...
