| Abstract | ||
| To study the influence of seed layer concentrations on the growth of ZnO nanostructures on silicon substrate using hydrothermal method. Seed layer was prepared with various concentrations of Zinc acetate dehydrate [Zn(CH3COO)22H2O]. The growth of ZnO nanostructures were conducted with 25mM of Zinc nitrate hexahydrate [Zn (NO3)2.6H2O],25mM of Hexamethylenetetramine[HMTA/(C6H12N4)] and 5mM of Polyethylenimine [PEI / (C2H5N)X] as a surfactant .The growth times were varied from 2-6hours at constant temperature (90ºC). The influence of seed layer concentrations and time on the resulting morphology of ZnO nanostructures grown were studied with FESEM. XRD was used for phase and crystal structure identifications. The seed layer concentrations were found to have the largest influence on nanostructures growth morphology and wire diameters with respect to the time. | ||
