Description

<jats:title>ABSTRACT</jats:title><jats:p>We studied on 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 on 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 started simultaneously and the laser ablation is stopped on the way of growth of ZnO nanorods. After the laser ablation is stopped, only 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 laser is only 0.023 Joule/cm<jats:sup>2</jats:sup>/pulse, the laser ablation shows remarkable effects on growth of ZnO nanorods.</jats:p>
