A ZnO nanowire resistive switch [PDF]

Applied Physics Letters, 2013
An individual ZnO nanowire resistive switch is evaluated with Pt/ZnO nanowire/Pt topology. A detailed DC I-V curve analysis is performed to bring both the conduction mechanism and the device characteristics to light. The device is further studied at various vacuum pressures to ascertain the presence of polar charges in ZnO nanowires as the phenomenon ...

Functionalised zinc oxide nanowire gas sensors: Enhanced NO2 gas sensor response by chemical modification of nanowire surfaces

Beilstein Journal of Nanotechnology, 2012
Surface coating with an organic self-assembled monolayer (SAM) can enhance surface reactions or the absorption of specific gases and hence improve the response of a metal oxide (MOx) sensor toward particular target gases in the environment. In this study

The nitridation of ZnO nanowires [PDF]

Nanoscale Research Letters, 2012
ZnO nanowires (NWs) with diameters of 50 to 250 nm and lengths of several micrometres have been grown by reactive vapour transport via the reaction of Zn with oxygen on 1 nm Au/Si(001) at 550°C under an inert flow of Ar. These exhibited clear peaks in the X-ray diffraction corresponding to the hexagonal wurtzite crystal structure of ZnO and a ...

Nanofabrication on ZnO nanowires [PDF]

Applied Physics Letters, 2006
ZnO nanowires were subjected to convergent electron beam irradiation in a 300kV transmission electron microscope. The size of perforated hexagonal pores generated by irradiation can vary with the beam size. An irradiated area is denuded layer by layer via removal of Zn and O atoms. The polar ZnO surfaces have a higher resistance to irradiation than the
