Abstract: | We report on the high-pressure pulsed-laser deposition growth of periodic arrays of free-standing single zinc oxide nanowires with uniform hexagonal arrangement and cross-section with thickness of less than 100 nm. In order to achieve the wire alignment, we prepared an ordered array of catalytic gold seed particles by a nanosphere lithography mask transfer technique using monodisperse spherical polystyrol nanoparticles. These templates were investigated by scanning electron microscopy and atomic force microscopy prior to nanowire growth. X-ray diffraction revealed the epitaxial relationships between the nanostructures and the a-plane sapphire substrate and excellent crystal quality. The optical properties of the ZnO nanowire arrays were measured by cathodoluminescence. PACS 61.82.Rx; 81.05.-t; 81.05.Dz; 81.10.-h |
