- Abstract
- We report on comparative investigations of ZnO thin films and nanowires grown on SrTiO3 (STO) single crystal substrates. Using pulsed laser deposition technique, we could grow ZnO thin films with (1120)- and (0001)-orientations on (100)- and (110)-orientated STO substrates, respectively. ZnO nanowires, grown by vapour condensation method with Au catalyst layers, did not show preferential alignment on either of the STO substrates. When the ZnO(0001)/STO(110) film was used as seed layer, we obtained dense and vertically aligned nanowires. Whereas, few and inclined nanowires were grown on the ZnO(1120)/STO(100) film. We discuss possible origins to cause all the observations. (c) 2007 Elsevier Ltd. All rights reserved.
