Abstract
ZnO nanorod arrays have become to attract much attention because the uniform and symmetry of ZnO nanorods can provide great optical and electrical potential in many nanodevices. Here, we have controlled nucleation sites using electron beam lithography technique and grown ZnO nanorods via hydrothermal synthesis to observe growth behaviors. We have measured nanorods's diameter and density of each aperture area. The results are presented strongly effect of aperture size and distance between adjacent apertures for growth ZnO nanorods. The both of aperture size and distance affect not only nanorod's density and diameter but also nucleation growth and growth rate. There is no nanorod growth through aperture area when aperture size is large and distance between apertures is small. In the same growth condition, there are several nanorods growth through large aperture size with large distance between apertures. These phenomena show behavior of ZnO nanorods growth with difference aperture size and distance which are useful to enhance great properties ZnO nanorods and also achieve high performance of nanodevices. ฉ Published under licence by IOP Publishing Ltd.
