Abstract
The possibility of diameter optimization of ZnO nanowires by using statistical design ofexperiment (DoE) is investigated. In this study, nanowires were synthesized using avapor–liquid–solid (VLS) growth method in a horizontal reactor. The effects of sixsynthesis parameters (synthesis time, synthesis temperature, thickness of goldlayer, distance between ZnO holder and substrate, mass of ZnO and Ar flow rate)on the average diameter of a ZnO nanowire were examined using the fractionalfactorial design (FFD) coupled with response surface methodology (RSM). Using a2III6−3 FFD, the main effects of the thickness of the gold layer, synthesis temperature andsynthesis time were concluded to be the key factors influencing the diameter.Then Box–Behnken design (BBD) was exploited to create a response surfacefrom the main factors. The total number of required runs for the DoE process is25, 8 runs for FFD parameter screening and 17 runs for the response surfaceobtained by BBD. Three extra runs are done to confirm the predicted results.
