ABSTRACTWe fabricated well-aligned ZnO nanorods with thin diameter by two-step chemical vapor deposition method combined with laser ablation of a sinterd ZnO target. Firstly, well-aligned ZnO nanorods with thick diameter of about 110 nm are grown on an n-Si (111) wafer. Next, a thin ZnO nanorod with about 30 nm diameter is grown on the center of the flat tip of each well-aligned and thick ZnO nanorod by controlling a flow rate of oxygen. Although thick ZnO nanorods do not emit a recognizable field emission current, thin ZnO nanorods with 1500 nm length show a field emission current of 500 μA under an electric field of 31 V/μm.
