Synthesıs Of Iı-Vı Group Nanostructures

In this study, II-VI Group ZnO Nanostructures were synthesized using vapor phase growth techniques and the effects of process parameters on synthesized structures were investigated with the aim of understanding the growth behaviour of nanostructures.


Evaporation temperature zone of zinc, type of Si-substrate, thickness and type of catalyst film, type of carrier gas, O concentration of carrier gas, temperature of substrate and process duration were changed in a systematic order for each process. As a result of the changes of these parameters, different type of nanostructures such as nanowire, nanorod, nano tetrapod, nanocomb, nanoinjector, nanoaeroplane and nanoclusters were obtained, and morphological and structural characterization of these structures were investigated using XRD, SEM, EDS analyses techniques. Processing parameters and their effects on the morphology of the ZnO nanostructures were produced and also categorized.
The results showed that, the thickness and type of catalyst film, the concentration of O in the carrier gas, the substrate temperature and process period have pronounced effects on the morphology of the synthesized nanostructures.
