Fast vertical growth of ZnO nanorods using a modified chemical bath deposition

• We grew vertical ZnO nanorods by a modified CBD process with a fast growth rate.
• We studied the effects of the CBD process by varying growth temperature, time, and concentration.
• The ZnO nanorods grown by the modified CBD showed good morphological and structural properties.

In this study, we grew vertical ZnO nanorods on seeded Si (1 0 0) substrates using a modified chemical bath deposition (CBD). We investigated the effects of the growth temperature, growth time and concentration on the morphological and structural properties of the ZnO nanorods using field emission gun scanning electron microscopy (FEG-SEM) and X-ray diffraction. This modified CBD method shows improved results over conventional CBD. ZnO nanorods with good structural XRD properties were grown with a very fast growth rate in a wide range of growth conditions and did not require post-growth annealing.
