Abstract

ZnO nanocrystals have received much attention as building blocks for nano/micro-devices due to their unique morphologies, electronic and optoelectronic properties. In order to apply the ZnO nanocrystals to the practical optoelectronic applications, control of the growth density, shape and position is required. We have achieved density-controlled ZnO nanowires and periodic ZnO nanostructures using laser interference patterning. Various shapes of ZnO nanostructure, such as microcylinder and aligned nanowall, were grown using interference patterned film and substrate. In addition, optically pumped ultraviolet lasing from a piece of the ZnO nanocrystal was achieved.
