Growth Behaviors of ZnO Nanorods Grown with the Sn-Based Bilayer Catalyst-Covered Substrates
Figure 4
Surface morphologies of ZnO grown at 700°C for 2 h on (a) untreated, (b) 700°C preannealed, and (c) 850°C preannealed Sn/Au substrates by thermal evaporation with a Zn mixture of Zn and ZnO in a weight ratio of 1 : 1.
