Fabrication of ZnO nanowires and nanorods

Physica E: Low-dimensional Systems and Nanostructures, 2012
Abstract In this study, we focused on the fabrication of two types of ZnO nanostructures, nanorods and nanowires, using different techniques. ZnO nanowires were fabricated by cathodically induced sol–gel electrodeposition using an anodic aluminum oxide (AAO) template. ZnO nanowires were approximately 65 nm in diameter and 10 μm in length.

Preparation and characterization of ZnO nanowires

Physica E: Low-dimensional Systems and Nanostructures, 2004
Abstract We have successfully synthesized self-organized zinc oxide nanowires on a Cu metalized silicon substrate by a modified reactive evaporation method by using a newly designed substrate holder. Characterizations were carried out by X-ray diffraction, scanning electron microscopy and photoluminescence measurements. Typical diameter and length of

Diffusion thermopower in ZnO nanowires

AIP Conference Proceedings, 2014
Low temperature acoustic phonon limited diffusion thermopower (Sd) in wurtzite ZnO nanowires is studied considering inelasticity of the scattering. An expression for scattering rate due to piezoelectric (PZ) acoustic phonon coupling is given. Sd calculated in elastic approximation, used in literature, is found to overestimate.

Tuning the growth of ZnO nanowires

Physica B: Condensed Matter, 2011
Abstract ZnO nanowires (NWs) with different diameters were obtained by controlling the particles of ZnO sub-layer (SL) exploring hydrothermal method; the diameter of the epitaxial NWs could be tuned from 60 to 146 nm when using SL with a thickness of 70 nm. The thickness of the SL would influence the orientation of the NWs.

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)
