Abstract

In the present paper, we synthesized highly ordered titanium (Ti)-doped ZnO nanorod arrays utilizing a facile hydrothermal method and a polystyrene nanosphere monolayer mask. The crystalline phase and morphology of the as-prepared samples were investigated systematically. The field emission (FE) properties measurement demonstrated that the Ti-doped ZnO nanorod arrays exhibited a significantly improved field enhancement factor β as well as a lowered turn-on field and a lowered threshold field. These improved FE performances were attributed to the decreased work function which resulted from the widened energy gap combined with the up-shift of Fermi level in n-type Ti-doped ZnO nanorod arrays.
