were used for the depositing. The influences of depostion potential and buffer layer on the preferred orientation and density of the ZnO nanorods were investigated by scanning electron microscope (SEM) and X-ray diffraction (XRD). A significant variation of density and orientation of ZnO nanorod arrays were obtained by changing the deposition time of buffer layer. Pre-deposition ZnO buffer layer relieved the lattice mismatch between ZnO and ITO substrate
and also provided the nuclei centers for the ZnO nanorods. SEM and XRD data showed that ZnO nanorods with the highest density and best
