Using the ZnO nanowire emitters with the photoconductor as the anode, the concept of a light-responsive field emission display (FED) was demonstrated. The brightness of display can be automatically increased with the increasing of external light-intensity. Additionally, the photo/dark current ratio can be controllably adjusted by changing the device parameters. The response of conductivity of photoconductor...
ZnO nanowire field emitter arrays with non-coplanar focus electrode structure was designed. A simulation was conducted to verified the focusing ability of the focus electrode structure. The designed structure was realized successfully and the growth condition of ZnO nanowires in the structure was studied.
ZnO nanowires have potential applications as large area field emitters for plat panel x-ray source and high emission current is needed for such application. In this study, patterned ZnO nanowires with different separations have been fabricated on ITO coated glass substrate by thermal oxidation technique. It is found that the separation of the patterns affects the growth of ZnO nanowires. The field...
Fluorine doping of ZnO nanowires was realized by using a biased CF4 plasma treatment. The morphology, work function, electrical characteristics and field emission properties of ZnO nanowires were investigated before and after CF4 plasma treatment. Though lowered work function and resistance were observed, the ZnO nanowires exhibit higher turn-on field after CF4 plasma treatment. The results were explained...
The temperature dependence of field emission characteristics from ZnO nanotrees is studied. An evident thermo-enhanced field emission effect is found in field emission from ZnO nanotrees. The turn-on field decreases obviously from 15.3 MV/m to 11.9 MV/m when the temperature increases from 293 to 773K. A defect-assisted emission model is used to explain the results.
In the present work, we presented our findings on enhancing field emission of low temperature solution phase grown ZnO NWs by using diamond like carbon (DLC) thin film.
