The induced growth of asymmetric nanocantilever arrays on polar surfaces was discussed. It was found that the Zn-terminated ZnO polar surface was chemically active and the oxygen terminated polar surface was inert in the growth of nanocantilever arrays. Longer and wider 'comblike' nanocantilever arrays were found to be grown from the Zn surfaces. The results showed that the surface polarity was important parameter in controlling the shape of ZnO nanostructures.
