“…Some nanorods have stopped growing. Similar phenomena were also observed by Miyashita et al [10] in the ZnO nanorods prepared by the CVD method. They reported a 'collision' between two non-parallel ZnO nanorods during the growing process.…”

“…Figure 2 shows SEM images of top view and perspective view of a sample fabricated without (1) laser ablation when t CVD is 3 min. These nanorods shown in figure 3-(3) continue to grow when the CVD is successively performed as reported in [9] for 15 min of t CVD . Further, the nanorods start to grow directly from the surface of the substrate.…”

We studied effects of laser ablation on morphology of ZnO nanorods fabricated by low-pressure thermal chemical vapor deposition combined with laser ablation of Mn. In this paper, we studied the effects of laser-ablation time period and energy density of laser beam at an initial stage of growth of ZnO nanorods. Both of laser ablation and chemical vapor deposition are simultaneously started, and only laser ablation is terminated after a certain period of time. After the laser ablation is terminated, chemical vapor deposition is continued. It is concluded from the experimental results that even if laser-ablation time period is only 30 sec and energy density of the laser is only 0.023 Joule/cm 2 /pulse, the laser ablation shows remarkable effects on growth of ZnO nanorods.

We study on electrical and light emitting characteristics of ZnO nanorods array when an electric field is applied in lateral direction to the axis of ZnO nanorods. ZnO nanorods grown on an insulator substrate are isolated with each other, i.e. there is no continuous nucleation layer of ZnO at the base of nanorods. When the applied lateral electric field is weak, no electric current and no light emission are observed. When the electric field becomes strong, however, an electric current begins to flow and bluish white light is emitted in the form of many streaks. These light streaks start from cathode and travel in all directions.
