Abstract

We report growth of ZnO nanostructures on Au-coated Si substrates using vapor phase transport in the temperature range from 800°C to 1150°C. Nanostructures grown at 800°C are rod-like with diameters of ~ 200 nm. Growth at higher temperature shows a more complex behaviour with 2-D structures connecting 1-D nanorods at intermediate temperatures and 3-D growth at the highest temperatures. Our work indicates that it may be possible to systematically control the growth mode and morphology of ZnO nanostructures by tuning the growth temperature.
