ZnO nanowall networks grown on DiMPLA pre-patterned thin gold films

Authors


Abstract

ZnO nanowall networks grown by a high pressure pulsed laser deposition (PLD) technique on a pre-patterned thin gold film are presented. The thin gold film on a c -plane oriented sapphire substrate was structured with diffraction mask projection laser ablation (DiMPLA). It is shown that only areas processed with the laser patterning technique reveal homogeneous growth of ZnO nanowall networks. Photoluminescence measurements prove the higher material quality of the pre-patterned regions compared to the untreated ones. (© 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
