Chemical and electric field assisted assembly offer a great opportunity in creation of heterostructures in multicomponent systems and in manufacturing of nanodevices. In this work, we report a new electric-field assisted assembly technique used to align individual ZnO nanowires on the Si substrate. During the assembly process, the forces that induce the alignment are a result of the polarization in the applied electric field. The synthesis was realized at low growth temperature which is necessary from a technology point of view. Novel experimental measurements on these structures show encouraging characteristics for future applications. The phase purity and composition of the synthesized products by the assembly method was examined by XRD and EDX. SEM has been used to examine the surface morphology and to estimate of the obtained structural sizes. TEM was employed to characterize the ZnO nanorods, and to observe the nanostructures. Room-temperature micro-Raman spectroscopy was performed to examine the properties of the self-assembly ZnO nanorods on Si substrate structures. Such highly oriented and ordered ZnO nanorods could be beneficial for field emission, solar cells, LEDs and spintronic applications. | | ISBN: | 978-1-4200-8503-7 |
