Abstract
ZnO nanostructures were produced with an innovative and simple vacuum thermal evaporation method with evaporating Zn in the presence of strong static electric and magnetic fields perpendicular to each other. These evaporated Zn thin films were oxidized in the furnace to obtain ZnO. In order to investigate the effects of magnetic field on ZnO nanostructures in this method, two different setups with different magnetic field strengths were assembled. Morphology and structure of ZnO thin films in both setups were investigated by micrographs prepared by field emission scanning electron microscope (FESEM) and X-ray diffraction (XRD) analysis. Results show that grown nano rods of ZnO in both setups are blade-like and match-like. Increase in magnetic field, changes the dominant type of nano rods from blade-like in weaker magnetic field to match-like in stronger magnetic field. Also increasing magnetic field strength causes different crystalline orientation in ZnO nanostructures. The results suggest that morphology and structure of ZnO thin films are affected by applying magnetic fields with different strength during deposition of Zn in this innovative method.
