Hi Brishty,

Please find some of the references which explained Zinc Oxide nanowire growth. Hope this information may help you.

Dear Mallikarjuna Reddy Kesama , thank you so much for the suggestions.

Dear Brishty,

In order to grow nanowires on substrate surface one has at first produce at the surface nucleation centers where the growth of nano wires start formation. These seeding centers can be in form of pits or aggregates of metals collecting the deposited material from the solution or the gas phase. It is a form of catalyst.

Best wishes
