Effect of metal catalysts type and annealing time on the growth of zinc oxide nanostructures by thermal vapor deposition method

This paper reports the results of zinc oxide (ZnO) nanostructure growth on different types of metal catalysts, namely gold and platinum, and also the effect of annealing time of the metal catalysts prior to the deposition of ZnO nanostructures. The metal catalysts layers with 15 nm thickness were de...
