Abstract

In this study, the ZnO nanorod is grown on the seed layered glass substrate by applying an external electric field to fabricate the ZnO nanorod with the high quality and to increase the yield of the ZnO nanorod. It is possible to grow the definite and clear hexagonal ZnO nanorod as the cathode of the high voltage is connected to the side of the seed layered glass substrate and the anode is connected to the opposite side because more $Zn^{2+}$ ions are located around the ZnO seed layer and are accumulated easily due to the external electric field. As a result, it is succeeded to fabricate the definite hexagonal ZnO nanorod having better structural characteristics by applying the external electric field during the growth process. Therefore, it is demonstrated that the external electric field is effective to fabricate the high quality ZnO nanorod without changing any composition of the ZnO nanorod.
