Optimization of Gated ZnO Nanowire Field-Emitter Arrays by Tuning Pixel Density

Gated nanowire field emitter arrays (FEAs) have potential applications in vacuum microelectronic devices. In this study, a coaxis-gated ZnO nanowire FEAs structure with an in-plane focusing gate was optimized by tuning the pixel density using simulation. Gated ZnO nanowire FEAs with optimal parameters was designed and fabricated. Their emission characteristics were studied.
