Fig. 1 AFM images of ZnO buffer layer, (a)asgrown surface and (b) laser-irradiated surface. We have succeeded in controlling growth density of the ZnO nanowires by introduction of a ZnO buffer layer. Low-density hexagonal cone-shape ZnO cores are formed on the buffer layer, and vertically-aligned ZnO nanowires are grown on the cores. The density of the nanowires was decreased by laser irradiation to the buffer layer before growth of the ZnO nanowires. In addition, periodic growth of ZnO
