Crystal orientation-ordered ZnO nanorod bundles on hexagonal heads of ZnO microcones: epitaxial growth and self-attraction

摘要

We demonstrate a preferential nucleation,epitaxial growth,and self-attraction of crystal orientation-ordered ZnO nanorod bundles on (0001) plane of single-crystal ZnO microcones.Recent developments in nanoscience and nanotechnology have not only brought potential building blocks for nanoscale electronics and optoelectronics,but also offer an opportunity to study and imitate biological functions at the nanoscale.
