Abstract

Vertically aligned ZnO nanowires have been successfully synthesized on sapphire substrates by a catalyst-free nanoparticle-assisted pulsed-laser ablation deposition (NAPLD) in Ar background gas. In NAPLD, the nanoparticles formed in the background gas by laser ablation are used as a starting material for the growth of the nanowires. These nanowires were used as building blocks for an ultraviolet light emitting diode (LED) with a structure of n-ZnO/ZnO nanowire/p-GaN In order to realize homo p-n junction using ZnO nanowires for efficient LED, we have also investigated the synthesis of doped ZnO nanowires by NAPLD for homo p-n junction.
