Two-tier rod of zinc oxide

Two-tier rod of zinc oxide

 Since the lattice constant on the C-face of a crystal of zinc oxide nanorod is similar to the lattice constant of sapphire, epitaxial growth on a sapphire substrate is possible, and it results in the growth of highly oriented ZnO nanorods.

Thinner rods sometimes grow at the tip of ZnO rods and form two-tier rods.
