Creation of novel ZnO nanostructures: self-assembled nanoribbonanoneedle junction networks and faceted nanoneedles on hexagonal microcrystals

摘要

ZnO nanoribbonanoneedle junction networks and faceted nanoneedle-microwhisker structures were grown for the first time by the evaporation of ZnS in the presence of oxygen under different reaction conditions. The nanoribbonsanoneedles crossed each other in three specific directions to form network-like 2D junction structures and displayed a unique and perfect growth mode. For the faceted nanoneedle structure, the nanoneedle grew epitaxially on the (0002) plane of a ZnO microcrys-tal. These ZnO nanostructures might have potential applications in the development of nanoscale electronics and optics.
