Synthesis and field emission characteristics of bilayered ZnO nanorod array prepared by chemical reaction.


The uniform, large-scale, and bilayered ZnO nanorod array on silicon substrate has been synthesized by a catalyst and template-free chemical reaction in a dilute solution. The effect of different precursor ZnO films on the morphology and size of the ZnO nanorod array has been investigated. Moreover, the morphology evolution of the ZnO nanorod array with the… (More)
