Abstract
In this present research, vertically aligned ZnO nanorods arrays were grown on silicon wafer (100) substrates from a zinc nitrate hexahydrate and hexamethylenetetramine solution by a cost effective and low temperature (90 ฐC) hydrothermal growth method. Field-emission scanning electron microscopy (FE-SEM) and X-ray diffraction (XRD) were used to analyze morphology, crystallinity and film thickness, respectively. It was demonstrated that when the seed layer thickness change from 18 to 200 nm, the nanowire density increased. Our result presented a scalable method for fabricating ZnO nanorods arrays with potential for a lots of application such as micro/nanosensors and the nanoelectronic devices. ฉ (2013) Trans Tech Publications, Switzerland.
