We demonstrate here a method for tuning the field emission properties of site- and area-density-controlled ZnO nanorod array using an aqueous process assisted by nanosphere lithography. The ZnO nanorods were grown on the hexagonally arranged circular patterns surrounded by nickel membranes on Si substrate. The synthesis process involved two main steps. First, an ordered monolayer film of polystyrene spheres was used to create nickel membranes with hexagonally arranged pores on ZnO-coated Si… Expand

Influence of ZnO nanowire array morphology on field emission characteristics.
It is found that a significant variation in nanowire height in an array also leads to a reduction in catastrophic damage observed on samples during field emission because arrays with highly uniform heights are found to suffer significant arcing damage. Expand
