| Abstract: | Parallel intersect wurtzite ZnO nanowires has been achieved firstly by free-catalytic thermal evaporation of ZnS powder onto Si substract. A Vapor-Solid process is proposed for the formation of ZnO nanostructures. XRD analysis and SEM observations revealed the nanowires were smooth and uniform throughout their length and perfectly single crystalline with wurtzite ZnO nanostructures. The as-synthesized nanowires have a length of several tens of micrometers and a width of several hundreds of nanometers. The growth mechanisms of these as-synthesized ZnO nanowires are also discussed. |
