Pulsed laser deposition was used to fabricate highly oriented Ga-doped ZnO nanorod arrays on GaN and sapphire substrates. X-ray diffraction showed that these nanorods were grown epitaxially with the c-axis normal to the substrate. The nanodots served as nucleation sites for the subsequent electric-field-assisted growth of nanorods.
