ZnS nanostructures have been fabricated over multi-layered graphene substrate via chemical vapor deposition technique. A controllable morphology of grown ZnS nanostructures, including (1D) nanowires, (2D) discs and nano-flakes were achieved by direct carbo-thermal evaporation of (1:1) ZnS and graphite powders mixture. The substrate location and therefore its temperature was found as a crucial growth parameter, which controls the morphology of the grown ZnS Nanostructures. The average diameter of the ZnS 1-D nanowires, at T= 400 °C, 2-D planar filling nano-discs, at T=300 °C, are 0.418 ± 0.007 μm, 0.600 ± 0. 020 μm respectively. At lower substrate temperature, <300 °C, a periodic round shaped features or flakes with some nanowire at their edges were for... view more»
