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...
The feasibility of preparation of nanowire on glass favors the realization of large area devices, which makes nanowire field emitter arrays (FEAs) good candidate for large-area vacuum microelectronics applications. In this study, a coaxial gated ZnO nanowire FEAs was fabricated. Effective emission current modulation by the gate voltage was achieved and the addressing capability was demonstrated.
